Global Head of Machine Tools at Siemens

Dear reader,

The current economic crisis presents all of us with considerable challenges,

particularly in the fi eld of machine tool manufacturing. Companies need to come up

with innovative ideas that can quickly tap into cost-saving potentials while

simultaneously providing investment security.

To signifi cantly increase productivity with innovations, you simply have to have

technological expertise. Another essential factor is a holistic view from the design and

production of machine tools through to commissioning, sales and service. This is the

only way to save time and money for the machine tool, and the parts produced on it

and, as a result, increase productivity.

This is where we can help by providing machine manufacturers and their customers

with innovative products and solutions – in 2009 especially. We see it as our main

objective to anticipate, adopt and initiate technology trends for machine tools at an

early stage. Consequently, we will be showcasing many innovations at this year‘s EMO,

plus three key innovations:

• Sinumerik 828D – the new powerhouse in the compact class

• Sinumerik MDynamics – the all-in-one technology package for milling

• Sinumerik Operate – the new integrated programming and operating interface

These innovative products are complemented by solutions for both machine tool and

workpiece lifecycle management and improving energy effi ciency. Siemens provides

energy-effi cient machine equipment and services ranging from the infeed to the

motor. Comprehensive energy management on the controller maximizes savings.

Together with our colleagues from Siemens PL, we open new horizons in the CAM-

CNC chain and offer continuity between the virtual world and the real world in terms

of the planning and operation of machine tools and production.

If you want to fi nd out more, why not read this issue of motion world? We hope you

enjoy it.

Sincerely yours,

The new Sinumerik 828D complements the

unique, consistent Sinumerik CNC portfolio

for every production-related task.

The fi nancial crisis has left its mark on virtu-ally all areas of the economy, and the machine tool market is no exception. The best oppor-

tunities for surviving the crisis relatively unscathed can be found in innovative concepts for the manufac-turing industries – including shopfl oor production, tool- and mold-making, the aerospace sector, power engineering as well as the automotive industry and medical part production. All these industries share a common trait: They have to utilize new and innova-tive machine tools to implement forward-looking projects, be it for machining processes, such as mill-ing, turning and grinding, or for forming and laser cutting. Automation and drive technology is crucial in all of these processes.

Integrated technology for all machine tool applications

The unique CNC portfolio unveiled at this year’s EMO in Milan features impressive universality, robust-ness, openness, modularity, scalability and ease-of-operation. Through integration into a continuous CAD-CAM-CNC chain, Sinumerik enables productiv-ity gains right from product design and tool setup. Considerably shorter implementation times are an-other benefi t, a great advantage especially with time-to-market becoming increasingly important in inter-national competition.

The core components of the Sinumerik platform are the CNC controllers. Machine manufacturers can choose from three categories – entry-level, compact and premiums, so there is a matching Sinumerik ma-chine tool control system for the specifi c require-ments of the machine tool operator. All Sinumerik solutions are equipped with drives from the Sinamics S120 drive series and matching motors.

Even the entry-level CNC control system, the Sinu-merik 802D sl, provides all functions necessary for the main applications in three-axis turning, milling, nibbling and grinding. The open and fl exible Sinumerik 840D sl CNC system represents the high-

performance or premium class of CNC systems from Siemens. It features a distributed, scalable, fully open and network-capable architecture. Its wide range of functions makes it suitable for use with vir-tually all kinds of technology, for up to 31 axes.

The brand new Sinumerik 828D is positioned right between these two performance levels. With its com-pact, strong and simple design, it sets new standards in the compact category of CNC systems. The 828D has extremely small dimensions so it can be easily integrated into the most compact of machines with-out compromising usability and performance. 80-bit

The MDynamics tech-nology package provides the latest technology-ori-ented milling solutions for both the Sinumerik 828D and the Sinumerik 840D sl. For the Sinumerik 840D sl, Sinumerik MDynamics is available in both a fi ve-axis and three-axis version. The new, compact Sinumerik 828D CNC already includes a technology package for three axes.

CAD/CAM system, the parts program and the ma-chine data of the CNC. In the production of models and molds, the expenditure incurred by this coordi-nation is fully included in unit costs. With Advanced Surface, this expenditure is completely eliminated as an innovative look-ahead capability, a new online compressor for NC data and harmonization of the speed profi les of adjacent milling paths, which works reliably even in line-by-line milling with alternating machining directions, all guarantee excellent surface quality even at high feed rates. According to the model and mold builders in Sindelfi ngen, these set-tings that are optimized just once in the post-proces-sor. The CNC works fi ne with plastics, aluminum and CFRP, i.e. the machining quality is the same for all materials. This means that the machine dynamics is enhanced overall and can be focused on achieving maximum roughing-down performance, high-preci-sion contour machining or optimum surface quality by activating the Cycle832 high-speed setting in the parts program. The effi ciency of the business pro-cesses on the shopfl oor is measured and monitored using the work orders stored in SAP and the number of parts delivered.

Familiar operation

In addition to this innovative functionality, operation of the new portal milling center also helps boost pro-ductivity. The machine operators confi rm that the Handtmann machine and the Sinumerik CNC are very simple to operate: machine tool setup is sup-ported by graphical tools with practical functions for measuring the tool and workpiece. In addition, the measuring cycles, such as “Align Cavity, Bore and Level”, speed up the process for setting or monitor-ing the zero point, thereby saving on setup time. The same measuring cycles can also be used to monitor the workpiece during the machining process.

Versatile technological functions support the operator

The Sinumerik 840D sl with its new technology pack-age offers a particularly wide range of support tools for model and tool and mold making, for example in the form of simple data transfer via Ethernet, Com-pact Flash (CF) card or the USB port on the front panel – from three-axis to fi ve-axis machining. This means that even large-scale NC programs can be eas-ily imported and processed directly by external data carriers. The machine operator is also supported by innovative cycles and milling strategies from the fi eld of CAD/CAM, such as trochoidal milling of hard materials, plunge milling at high chip volumes (high-performance cutting or HPC), special cycles for multi-axis and/or multilateral machining and frames for implementing turned and swiveled coordinate sys-tems. For the most accurate milling results, the cycle Measure Kinematics Cycle996 is used to control ma-chine accuracy with this CNC. Cycle996 uses a mea-

suring probe and measuring sphere to measure the entire kinematics of the rotational axes and, where applicable, to correct any erroneous axial vectors. The new machine also demonstrated that effi cient production of models and molds is virtually unthink-able today without an integrated process chain from CAD-CAM level to CNC level. A CNC such as the Sinu-merik 840D sl with Sinumerik MDynamics, which uses a single optimization procedure for all machin-ing types and production tasks, offers decisive ad-vantages in this respect. It ensures stable conditions at the end of the process chain, which greatly simpli-fi es the work carried out in the CAM system, makes the results more reliable and maintains manufactur-ing productivity at a consistently high level.

On the right path with the new Sinumerik

After about six months of use in a full production en-vironment, the Sindelfi ngen-based operators work-ing with the Handtmann Gantry RS and the innova-tive functionality of the Sinumerik 840D sl feel very confi dent about the new technology. The standard CNC fulfi lls the requirements of the demanding model and mold-making process, and it offers the openness and fl exibility required by modular tool making and special machinery construction. To-gether with Totally Integrated Automation, Safety In-tegrated and an integrated process chain, the solu-tion yields very high benefi ts for machine tool makers and manufacturing companies alike. p

Wincor Nixdorf AG, Germany p

One for All

W incor Nixdorf AG is of the world’s leading and most successful providers of IT so-lutions for banks and commercial enter-

prises. Its clear commitment to innovation in all ar-eas means that the company is also extremely well-equipped to cope with diffi cult economic peri-ods. And as Michael Schönbeck, Head of Technology Lines, points out, the company uses only the best technology available. Over the past few years, he has restructured the tool shop, where 65 employees man-ufacture around 300 tools per year for in-house use. In addition, the company performs machining work for external customers and in return buys in the ser-vices of other mold manufacturers. This leads to a high degree of fl exibility and optimum utilization.

Uniform control architecture

Tool making at Wincor Nixdorf is focused on complex fi nish-machining. Prefabricated master dies are pro-cured just-in-time and then have to be processed fur-ther with the same level of effi ciency. More than 15 years ago, Schönbeck clearly saw that milling would become the most strategic production method in his tool shop. High-speed milling machines can be used to produce surfaces that only require a minimum of fi nishing work. So he asked himself: which control systems were capable of achieving the necessary speeds while also offering the functionality to pro-cess the required volumes of data? As Schönbeck ex-plains, “We used to deploy a variety of CNCs, so we were able compare different products objectively based on experience. And of course we also took a close look at the current and future generations of controllers at the time.” Twelve years ago, the tech-nology manager took the decision to equip a milling machine with Sinumerik 840D sl. He was extremely

gram, the more important these features are. For several years now, Siemens has provided an ex-tremely user-friendly feature in the form of the Shop-Mill graphical user interface, which provides a quick and easy way of creating programs. Although this is only of limited importance at Wincor Nixdorf, where over 90 percent of the complex programs are created on external CAD/CAM workstations, it still provides valuable assistance to the machine operators: the setup and tool management functions it provides prove extremely useful when it comes to setting up workpiece setup. As Siemens consultant Ingo Bartsch says, “Our interface software is intuitive and features graphical animations, making setup so simple that even untrained employees can pick it up within a few days.” p

pleased with the results and soon established a uni-form control architecture throughout the entire tool shop, resulting in enormous benefi ts for the ma-chine operators and logistics alike.

The right machine tool for every task

Standardization is an important goal for Wincor Nix-dorf also in selecting machinery for the tool shop. Potential machine tool suppliers need to offer a wide range of products and provide a suitable solution for every machining task. The DMG Group, whose high-quality HSC 75 linear machining center with direct drives is used in electrode production at Wincor Nix-dorf, was selected to be the company’s partner. “After all, the best control system on the market is useless to us if the machine cannot achieve the required sur-face or is too slow,” explains Schönbeck. He is de-lighted with both the machining times and the sur-face quality achieved on the graphite and copper electrodes. “This machine virtually eliminates all fi n-ishing work, enabling us to achieve optimum pro-ductivity.” Based on its positive experience with the HSC 75 linear, Wincor Nixdorf went on to purchase a larger, equally powerful machining center for its ma-chining shop.

The company opted for the HSC 105 linear from DMG, which is ideal for medium-sized fi ve-axis parts. This machine has a very large working area in rela-tion to its overall size, and not only does the fork head provide a high level of machining freedom, but the axes also achieve impressive acceleration and speeds. This is made possible among other things through the use of 1FN3 linear motors, which bring signifi cant benefi ts in terms of precision, dynamics and acceleration. In order to provide optimum com-pensation for thermal infl uences and ensure clean swarf removal, Deckel Maho uses vibration-reducing material and intricately designed machine geometry. When working with short machining times, the inter-action of linear motors, machine geometry and Sinu-merik CNC ensures extremely high axis acceleration and speeds.

Powerful and user-friendly

Michael Schönbeck is absolutely certain that the Sinu merik CNC makes a signifi cant contribution to the results obtained; it is the “fastest control system both in terms of batch processing and cycle times.” Moreover, the confi gurable and programmable zero offsets – known as “frames” – are simple and fl exible to set and can be transferred to the machine at the touch of a button. And the more elaborate the pro-

Improved Surface Quality in a Flash

The surface quality of the workpiece is the most important quality feature in tool- and mold-making because it is immediately ap-

parent. Up to now, however, detailed optimization of the machining parameters has been the only way to achieve a perfect surface; the parameters have to be adjusted for almost every single part in accordance with the requirements of the workpiece. Adjusting the milling parameters is a critical factor in terms of production planning costs and effi ciency. “If a part takes 3.5 hours to machine, the machine operator wants to be sure that the quality of the fi nal product

With Advanced Surface, it is no longer necessary to spend time adjusting machining

parameters for piece production when making tools or molds.

is exactly as required. After all, if he has to spend hours on polishing after the machining process, his previous cost calculations become void,” emphasizes Markus Eisold, Managing Director of EiMa Maschinen-bau.

ity even at higher feed speeds – and without the need to optimize milling parameters for each individual part. Central to the success of this technology are the innovative Lookahead function and the NC data com-pressor, which has been revised and upgraded. To-gether, they ensure that neighboring milling paths have an identical speed profi le, even during alternat-ing line-by-line milling with different motion direc-tions. The new Lookahead feature also minimizes po-sition lag, guaranteeing high surface quality. The integrated jerk limitation feature and the COMPCAD online data compressor work together to ensure that the tool moves smoothly and fl uidly. By centralizing ISO program data sets in splines, it is possible to guide the tool smoothly and continuously within the tolerance range, achieving a signifi cant increase in contour accuracy at the edges. This all takes place without the need for the previously required expen-sive and time-consuming optimization.

Innovative reference machine …

A Gamma T linear machine from the German-based company EiMa was among those selected as a pilot and reference machine for testing the path control. By this time, the company had further refi ned many of the features of the portal milling center, which made its debut at the EMO 2007 trade fair. For exam-ple, the addition of a gear rack drive has improved the rigidity and crash resistance of the Z axis, and the rigidity of the tool guide during 3+2-axis machining has also been further improved thanks to hydro-pneumatic fi xed brakes in the fi ve-axis head. In addi-tion, higher-performance power units are now avail-able for Sinumerik 840D sl CNCs, opening the door to a new generation of spindles. Some 24 kilowatts of power and speeds of up to 22,000 RPM also serve to improve processing performance for high-volume cutting applications.

The new and convenient integrated Sinumerik user interface has also been installed in the machines as part of the pilot program for the new Sinumerik MDy-namics technology package. The interface combines the best features of existing user interfaces in this CNC, including the integrated ShopMill functionality that has been expanded to support multi-channel machining, and builds on them with key features such as setup in JOG, simplifi ed program data han-dling, convenient tool management, new innovative cycle technology and 3D simulation.

… in a successful pilot program

The performance improvements of the Sinumerik MDynamics technology package with the new Ad-vanced Surface path control system are obvious when

compared with existing standard CNC functionality: A sample part was fi rst machined using the “old” path control and without any further optimization of the milling parameters. The result demonstrated that, at critical points, there was room for improve-ment in terms of surface quality, contour accuracy and machining effi ciency. The milling parameters were then optimized step-by-step in the CAD/CAM system, in the part program and in the CNC machine data until the required surface quality was achieved. “We then activated the new path control,” recalls Markus Eisold, “and milled the workpiece for a third time, this time using the standard settings specifi ed at the commissioning stage with the help of a sample part; in other words, without optimizing them to the

individual part. The fi rst try produced results that were better than, or at least as good as, individual op-timization.” The manager of the electrical depart-ment at EiMa, Jörg Diez, summarizes the results of the pilot project as follows: “Machines like the Gamma T linear offer an increasingly interesting option for production of large-scale models and molds. The col-laboration with Siemens in this area has therefore turned out to be really benefi cial for us. It has al-lowed us as machine manufacturers to provide the best possible service to both special machine opera-tors and tool- and mold-makers. We feel confi dent that with Siemens, we found the right partner, par-ticularly in view of the new European machinery di-rective.” p

A Bridge Between Two Worlds

The tight integration of the Sinumerik CNC product line, production networking,

ensures that no information is lost between the virtual world of process planning

and the physical world of production operation.

The fundamental parts-manufacturing process involves two worlds: the virtual world of pro-cess planning (the design environment) and

the physical world of production operation (the job shop). Until now, one hurdle on the way to increasing production effi ciency was the fact that the virtual and physical worlds are normally only loosely con-nected. This creates a gap where knowledge and in-formation obtained during programming in the CAM environment is often lost, while many functions in controller are not fully utilized because they are not addressed correctly by the programming system.

Improvement of the CAM-CNC connection is there-fore a key aspect in parts production. However, in or-der to achieve optimum interaction between the CAM environment and production, the systems involved need to be able to “understand” one another; that is, information from the one world needs to be available in the other in a form that can be understood by the programmer or worker and, in particular, the infor-mation must be preserved during the transition from the CAM environment to the shopfl oor.

Continuous information chain from product design to manufacturing

Siemens is the only manufacturer able to offer a com-plete solution for the virtual and physical worlds of CNC production thanks to the combination of a pow-erful CAM environment – NX CAM – and an ultra-modern NC system – Sinumerik. Users benefi t from the tight integration of expertise in the fi elds of both NC and CAM technology. For example, Siemens sup-ports the programming of specifi c machining opera-tions with best practice libraries, which already con-tain typical features as self-contained, optimized production operations. This ensures that the CAM software “knows” that a certain workpiece with free-

formed surfaces can only be processed on a tool for simultaneous fi ve-axis machining and therefore pre-pares the correct tools and milling strategies.

Validation and optimization with control-based simulation

Processing simulation plays a key role within CAM-CNC integration. The Siemens package provides a solution that enables a realistic simulation of the NC program and allows it to use complex Sinumerik functions, e.g. special processing cycles, to optimum effect.

Following program creation, the program in the post-processor is converted into the relevant control format in NX CAM. Version 6 of NX CAM now con-tains special post-processor templates for the Sinu-merik CNC. The programmer can enter parameters for the control directly in special dialog areas within NX CAM. These parameters are then automatically converted into the corresponding Sinumerik cycle and are preserved in the post-processor run. The cor-responding Sinumerik parameters are correctly pre-set – generally through best practice templates in corresponding libraries. This means, for example, that at the start of programming, the programmer can call up a special confi guration for a machine in which the required parameters are already set, en-abling him to focus solely on the programming of tool paths.

In order to verify the fi nal NC program in the Sinu-merik dialect, Siemens has developed a virtual ma-chine, both in NX CAM and in Tecnomatix RealNC, that can be used during production planning or on the shopfl oor. This machine tool simulator is a digi-tal fi ngerprint of the actual machine: the virtual NC kernel (VNCK) is tuned using the real machine tool’s control parameters to make sure that the real and

virtual machines behave identically in terms of oper-ation, dynamics, warning and error display.

Optimized programming for Sinumerik

Two aspects in particular are relevant for making op-timum use of Sinumerik capabilities: programming of tool path processing and programming of the ad-vanced functions of Sinumerik.

In order to program the tool paths in NX CAM in such a way that they are automatically optimized, a CAM system is used that knows the geometric tool path data required and can distribute the points to suit the precise requirements of the CNC control sys-tem. One example: by synchronizing the data points in adjacent paths, the speed of the subsequent ma-chining in the CNC control system can be controlled more evenly and the feed can be optimized. This in-creases the machining speed as well as improves sur-face quality.

A further increase in effi ciency in terms of quality and processing time can be achieved if the powerful Sinumerik control system functions are used consis-tently by the CAM system. Programming is essen-tially made up of the workpiece geometry, the ma-chining step, the material of the part and the tool. This information is recorded in the NX CAM pro-cessing plan and is now used, for example, to set the correct High-Speed Cutting (HSC) technology pa-rameters on the Sinumerik CNC. Using the high-

speed cutting cycle CYCLE832, tolerance bands can be defi ned for machining, and functions such as smoothing, NC record compressor, pilot control or jerk limitation can be activated and deactivated in-dependently of the processing step. Similarly, it is possible to activate the correct control parameters for rough machining, rough/smooth machining or smoothing. This establishes a balance between the different requirements – precision, machining speed and surface quality – for each machining step. As Si-numerik users on the shopfl oor are familiar with these cycles, they can easily identify them in the Si-numerik HMI. They can understand sub-programs more easily as the system presents them with a clear overview of cycle commands rather thana vast array of machine-oriented G-code data. If required, the cycle parameters can also be adapted more easily to the control systems on the shopfl oor. There is also the option to transfer information that the worker has changed back to the PLM process. This increases both the knowledge base in produc-tion planning and effi ciency. p

The integration of production planning and actual production not only affects the actual production information. If you look at the complete parts pro-duction process, typically there are a number of special technologies used in each step. These sys-tems or software applications are not integrated into a common information platform. As a result, just answering the most basic of questions, such as “Am I using the latest version of the parts program? Has the parts fi le been changed? Is this the right tool list?” wastes considerable amounts of time. Siemens has now developed a solution that links the existing solutions for parts production planning and data management – NX CAM and Teamcenter – with the information management software for the shopfl oor from the Sinumerik Manufacturing Excellence portfolio. This means that all the information used throughout the entire process can be synchronized – from the defi nition and validation of the produc-tion plan right through to the use of this plan in the production process.

Data along the entire parts production process is managed and organized uniformly in Teamcenter: for the part/product concerned, the production processes used, required resources and machines,

system-specifi c or location information concerning the factory. This enables the user to signifi cantly reduce the number of ineffi cient processes and potential errors.

All of the information in one systemIn Teamcenter, all of the information concerning the parts production process is managed in a uniform way and is made available on the shopfl oor. This includes:

Energy effi ciency is becoming an increasingly hot topic in the fi eld of machine tool manufac-turing and operation. Wasting energy not only

costs money, but can cause thermal problems in the control cabinet and on the machine – ultimately im-pacting productivity and precision.

To save energy, we need to start at the machine it-self. Measures to enhance effi ciency here include dy-namic optimization of the mechanics and drive tech-nology assemblies and consumption-based optimi-zation of the moving masses. Within any work cycle, there are enormous differences in the amount of electrical energy required during individual stages of the process, for example between machining times and non-productive times such as rapid feed or tool changeover. During rapid feed, the drives need to ac-celerate and brake sharply, with the result that power consumption during this phase is between one- and fi ve-times higher than during actual machining.

Striking an intelligent balance between speed and productivity in this phase can signifi cantly cut power requirements.

Drives need power

The drive components have a massive impact on the overall power consumption of a machine. Electrical drive technology with intelligent, productive control algorithms and high effi ciency ratings can play a key role in keeping energy costs to a minimum through-out the lifecycle of a machine. Furthermore, all types of infeeds for the Sinamics S120 drive system are available with an energy recovery feature, whereby the energy released during braking is fed back into the network for use by other electrical equipment. Another feature that helps improve overall machine energy effi ciency is reactive power compensation. Si-namics infeeds with “Active Line Modules (ALF)” au-

tomatically compensate for the reactive power re-quired by the line fi lter, thereby ensuring that no phase shift occurs between voltage and current. In the best-case scenario, this completely eliminates all additional costs for separate compensation systems.

For maximum energy effi ciency, the dimensions of the infeed/recovery unit and/or the braking resistors need to be tailored as closely as possible to the sys-tem concept. This is where dynamic energy manage-ment sets in: it acts on the acceleration/braking ramp and the torque set-point of the selected drives to en-sure that the intermediate circuit values, voltage and maximum power remain within permitted values. This represents a safe way of harmonizing the in-feed, recovery and braking modules with the ma-chine and ensuring they are no larger than neces-sary. The application of this technology for emergency retraction and mains failure offers particular poten-tial for machine tools. Siemens is available to offer customers all the support and guidance they need in designing such systems.

Frequency converters and energy-effi cient motors pay off

Ancillary components on machine tools such as chip conveyors, pumps and compressors account for more than 50% of a machine’s base load in standby mode alone. This high level consumption is due to the fact that many of the drives are uncontrolled, fi xed-speed drives. Using frequency converters rather than con-ventional control methods can yield savings of up to 50%. No energy effi ciency concept would be complete without energy-effi cient motors. Turbo ma-chines are a case in point: as these machines need to be run at a constant maximum speed at all times – i.e. more than 2000 operating hours per year – use of energy-saving motors in effi ciency class EFF1 can re-sult in massive savings in terms of energy and elec-tricity costs.

Intelligent approach to power

Whether it be intelligent infeed technologies, use of frequency converters in ancillary components or en-ergy-saving motors, energy-effi cient automation and drive technology can provide a return on investment within a short period of time, signifi cantly cut en-ergy costs and, in turn, reduce unit costs, too. An ef-fective energy management concept is also impor-tant. Simply keeping a record of individual power fl ows is not enough, as this will save neither power nor money. Companies need to identify and evaluate potential savings and then use this information to in-troduce energy-saving measures. Only by investing in energy-effi cient machine tool automation systems will they then be able to minimize lifecycle costs and total cost of ownership. p

New motors

Main drives for belt-driven and coupled machine tool spindlesThe new 1PH8 motors are available in both synchro-nous and asynchronous versions. These motors boast impressive dynamics, minimal torque oscillations and high vibration quality, thereby enhancing the precision and productivity of machine tool spindles.

New linear motor The new 1FN6 linear motor features a magnet-free secondary section. The primary section is equipped with internal coils and magnets, is self-cooling and features separate plug connectors for pre-assembled signal and power cables.

High-inertia version for servomotorsThe proven 1FK7 servomotor series now has a new addition in the form of a high-inertia version. The higher intrinsic inertia on these versions results in an extremely robust control response, making them particularly suitable for applications with high and/or variable inertia loads. In conjunction with Sinumerik CNC, high-inertia motors can achieve out-standing contour precision without the time-con-suming process of adapting the controller to the ma-chine.

Ideal for Delicate Parts

Manual work has largely disappeared from the jewelry sector – nowadays high-tech machines are used to produce freely

formed surfaces with a mirror fi nish and fi t pieces with tiny diamonds. The requirements placed on the machine manufacturers are correspondingly high. Carl Benzinger GmbH of Pforzheim, Germany, makes precision machines that are accurate to less than a micrometer in terms of surface quality, roundness and positioning. The machines are used by all major companies in the watch and jewelry industry, as well as in other demanding sectors such as medical and dental part production, automotive technology, and the fi ttings and the aerospace industries.

Customer proximity defi nes machine development

The company with a staff of 140 people bases its suc-cess on its proximity to the customer. Benzinger of-fers a complete concept that includes process auto-mation with robot and application technology, along with services such as After-Sales. In terms of the ma-chines, the company sets great store by user-oriented development, as well as cost-effective production of high-precision workpieces from a batch size of 1 through to medium-sized series of around 5,000 units. The Take 5 combined turning/milling center fulfi lls these requirements effectively. The structure and arrangement of the axes on this machine series results in a particularly compact design, which re-quires about 50 percent less space than comparable turning/milling centers. The kinematics also has a positive effect on the machine’s precision. “As our customers often require simultaneous complete ma-chining of complex components, we equipped the Take 5 with an additional milling spindle,” explains electrical engineering manager Wolfgang Wiede-mann.

Sophisticated multi-channel technology for turning/milling concepts

To ensure reliable control of the various axes and machining technologies, the Baden-based precision

machine manufacturer is not prepared to accept any compromises when it comes to CNC technology. Several comparisons and tests revealed that the Sinumerik 840D sl is best suited to the turning/milling concept on the Take 5. It is profi cient in every machining technology, can control up to 31 axes, and has ten channels as standard. This is confi rmed by Wiedemann, who reports that, “The sophisticated multi-channel technology creates the perfect condi-tions for clear program structures, thus enabling simple programming for different technologies.” The Take 5 uses fi ve of these channels: turning on the main spindle, turning on the counter-spindle, mill-ing, tool change and turning with the milling spin-dle. This enables milling and turning to be carried out simultaneously in dif-ferent part programs. If necessary, a turning tool can also be fitted and clamped to the milling spindle so that various turning operations can then be carried out on the main and counter-spin-dles. “Our customers can carry out all of these func-tions flexibly with the Sinumerik CNC. Many other control system man-ufacturers would have problems”, adds Wiede-mann. Moreover, with the Sinumerik 840D sl, it is possible to carry out turn-ing and milling operations alternately in the same channel. As Siemens con-sultant Klaus Steinbrücker explains: “Alternatively, the tool holder can be used sequentially across chan-nels – i.e. from different programs. This means that all necessary transformations can be used, such as Transmit for front milling, cylinder barrel transfor-mation for surface-area milling, and fi ve-axis milling with dynamic orientation of the milling tool on the workpiece.”

The combined turning/milling center with two rotating spindles and a milling spindle is perfectly suited to simultaneous, complete machining of complex components

Simple, safe operation

In practice, the Take 5’s complex milling and turning programs are set-up for the most part at external workstations and transferred to the CNC via a net-work or USB stick. For simple programs and machine setup, users use the standard, clear control console, which is fi xed to a dual-joint support arm and can be swiveled. Thanks to the user interfaces with cycle-

supported screens, even technicians with little pro-gramming experience can get to grips with the sys-tem within the space of just a few days. If anything is unclear, an “electronic wizard” can be activated by means of the Help key to provide specifi c informa-tion. To ensure safe setup for the users, the Benz-inger developers use the “Safety Integrated” function integrated in the Sinumerik 840D sl. This safety func-tion provides reliable protection for the user, without the need for wiring mechanical and electronic circuit breakers. A further advantage is, for example, that if such a machine tool is fi tted with a robot later on, it can be adapted quickly and easily. In just a few min-utes, the user can create a part program that allows work to be carried out with the guard door open, that takes into account all necessary safety regulations, and that provides reliable protection against colli-sions. This saves on hardware, time – and ultimately, costs. p

Goratu Máquinas Herramienta, Spain p

Innovative Machining Strategy

Goratu Máquinas Herramienta, S.A. manufac-tures a complete range of CNC milling ma-chines and CNC lathes under the Lagun and

Geminis brand names. With almost 200 employees, the company is one of the largest Spanish machine tool builders and maintains global subsidiaries for sales and services. The wide product range responds to the needs of different industrial sectors addressed by the company, such as power generation (windmill shafts), aerospace, iron and steel, petrochemical, railway, and ship-building.

Combined technologies in single machine tools

With several thousand units installed globally, the company has long-standing experience in designing, engineering and manufacturing machine tools. Their newly-developed, multi-functional devices improve customer productivity in the manufacture of large-size components in different shapes, high quality and short time. Therefore turning and milling tech-nologies are combined into one unique machine. Such a unit allows the machining processes without the reclamping of workpieces. Doing everything in one clamping, that is, turning, milling and drilling, saves both on machines and alignment, including set-up steps, thus reducing resulting errors and time spent.

Basing on the two common manufacturing lines, Geminis for turning and Lagun for milling, Goratu offers a wide range of choices. Lagun CNC bed mills has been extended to customize the solutions ac-cording to individual production needs. For exam-ple, the GMM travelling column milling machines and the GCM travelling column milling machines with fi xed tables that are giving increased capacities.

Machine tool manufacturer equips new

multi-functional series for milling and

turning with Sinumerik 840D sl control

systems.

For heavier or larger workpieces, milling offers a solid table, allowing component weights up to 3.5 ton/m².

Powerful programming features

To provide customers not only high quality machines with fl exible milling and turning functionalities, but also with state-of-the-art control systems, the tool manufacturer decided to equip the new multifunc-tional machining centers with Sinumerik 840D sl. It provides functionality for the most varied technolo-gies and make it as simple as possible to use and con-trol complete machining on turn-milling machines. According to the Goratu management, Siemens con-trols are not only user-friendly, but they also offer powerful and versatile programming features. To get the best out of it, the company’s training academy of-fers courses for new and advanced Sinumerik opera-tors.

Goratu’s machines are modular in design and spe-cifi cally developed to perform a full range of machin-ing operations in a single setup, on a wide variety of materials. On the one hand, the latest developments on fl oor-type moving-column milling machines and on the other heavy CNC horizontal lathes, both in combination with Sinumerik controls. The machin-ing centers demonstrate state-of-the-art technology for the processing of complex workpieces. Virtually unlimited capacity is combined with the ability to manage large parts profi tably, delivering the versa-tility and fl exibility for large part machining. p

With Sinumerik 840D sl, customers gain a variety of signifi cant benefi ts, such as:

Multi-functionality 3 with optional function packages for the Sinumerik 840D sl controller: users can confi gure solutions for almost any machining task in turning, milling, drilling, circular milling, turn-milling, crankpin milling, B-axis turning and fi ve-axis machining with functions such as orientation interpolation, slotting, gear hobbing, curve table interpolation and cam milling.

Flexible programming 3 for optimum processes in turn-milling (and other technologies): fl exible and optimized processes can be achieved through synchronized motion actions that can be initiated synchronously with axis and spindle motions. Up to 256 such synchronized actions can be defi ned per part program.

Simple operation 3 with advanced HMI functions: in addition to standardized or user-generated screen forms and help graphics, Sinumerik 840D sl offers further HMI functions that make complex machining processes more transparent and therefore more easily controllable.

Specifi c post-processors 3 enable users to use the extensive possibilities of the multi-functional Sinumerik 840D sl fully and effi ciently during turn-milling.

Safe retraction 3 in case of error: with the drive-independent function “extended drive stop and retract” (ESR), Sinumerik offers a fl exible response to various sources of error. Safe retraction is enabled by defi ned, time-delayed stopping, and by tool retraction from the machining plane into a position where it is protected from collision.

High precision 3 for reliable production processes: innovative control/drive functions such as “dynamic stiffness control” (DSC), “active vibration damping/advanced position control” (APC) and “auto servo tuning” (AST) help achieve high precision and the greatest possible dimensional and geometrical accuracy during turn-milling.

Safety 3 is ensured with a package of safety functions that are integrated into the control/drive system. This integration enables very short response times. Communication with the process is performed directly using safety-related input/output signals.

Virtual machining 3 and prior simulation of machining tasks is recommended to achieve the greatest process certainty before the start of production with turn-milling. For these tasks, the Sinumerik virtual NC kernel (VNCK) solution can be integrated into simulation systems.

For turn-milling of large workpieces, Goratu has developed the multi-tasking

New manual for fi ve-axis machining

Milling with Sinumerik

The potential fi re risk of machine tools should be a serious concern. In many cases, a fi re breakout would not just affect the machine itself, but it could also spread throughout the entire production facility. The intelligent Sinorix al-deco STD object protection sys-tem has now been installed on a turning machine at the Technology and Application Center (TAC) in Er-langen, Germany and can be used for live demon-strations. The key component of the fi re extinguish-ing system is a tubular, patented linear fi re sensor called Lifdes (Linear fi re detection source), which is subject to a permanent pressure of approximately 15 bar and bursts as soon as its ambient temperature exceeds 110 °C. The fi re protection system does not require an external energy source to detect or extin-guish the fi re as both processes are pneumatic. The systems are highly resistant to all kinds of technical disturbances, resulting in negligible risk of false ac-tivation.

The Sinorix system measures the volume of extin-guishing agent online and monitors the pressure in the detection line, the operating status and the status of the network. All functions are displayed visually and acoustically via the interface, and there is a

backup battery to ensure continuity of the interface functions in the event of a power failure. In addition, all safety-related and operating data is auto matically logged to a memory on a long-term basis and can be read via a USB interface. This enables clear state-ments to be made in the event of liability disputes.www.siemens.com/sinorix

The Sinumerik 840D sl CNC offers a broad range of functions specifi cally for fi ve-axis machining. The new manual on fi ve-axis machining provides pro-grammers and machine operators with an overview of all important control functions, how to use them effectively and requirements for the CAD/CAM envi-ronment. The topics covered by the manual include an explanation of the basic terminology and require-ments of fi ve-axis machining, a description of the fundamental Sinumerik control functions, such as measuring and tool and workpiece, as well as an overview of the higher-level control functions that should also be taken into consideration with regard to the CAM system’s post-processor. The manual then concludes with industry-specifi c chapters on aero-space, structural components, engine and turbine components and complex free-formed surfaces – all explained in detail with graphical and practical ex-amples.

A manual on tool- and mold-making with basic in-formation on multi-axis machining is also available. This manual is particularly useful for three-axis ma-chining and also serves as a basis for fi ve-axis ma-chining.www.siemens.com/sinumerik
