• high quality programming of CNC machines for laser, plasma, oxy-fuel and water-jet cutting.

Database• Open database

Vintech RCAM-Pro automates the creation of cutting technologies by taking into account the specifics and requirements of every cutting type - laser, plasma, oxy-fuel, water-jet or mechanical. It saves information accordingly to the ongoing physical and chemical processes inside the cut, the type and thickness of the material and the type of the processed contour. The system supports all repeatedly used information for nesting in the SQL database, which is hidden for the user (i.e. system supportis not required). The information in the databaseis organised in accessible for overview and editing Datasets.

• Technological DatasetsVintech RCAM-Pro supports specific technology knowledge in Technological Datasets for Machines, Carriages, Torches, Gases, Post-processors, Types and Grades of materials, Producers, Processing technologies, Technology tables.

Vintech RCAM-Pro uses the datasets to select and apply the Processing technology to the project based on machine, material grade and thickness, processing type and length of the paths.

• Dataset PlatesSupports the geometry and the attributive information for rectangular plates and usable remnants. In the dataset, the plates are organised by criteria: material, thickness, standard, shape – rectangular or complex. The plates can be imported in the dataset trough direct input, from CAD files or trough saving usable remnants from nesting layout.

• Dataset BlocksSupports nested groups of parts, organised by material, thickness, machine, energy source, tool and kerf. It is used in repetitive production of parts from the same product.

• Datasets with norms for work and materials

Supports normative data, which is necessary forpricing and creating offers in the datasets: Prices for materials and processing, Company details of customers and suppliers, Additional expenses, Delivery conditions, Settings for pricing.

Nesting Geometry• Geometry Import

Vintech RCAM-Pro 9 reads CAD files with DXF, SVG, ESSI or DSTV formats and imports CAD geometry for parts and multi-parts. The CAD geometry can contain arcs, segments, ellipses, splines, point sets and text. The system automatically corrects geometric defects and marks the parts with remaining errors. It recognises the contour type in the parts as: Outer, inner, hole, slit, geometry for marking and point sets. Allows manual change, inclusion and exclusion of processing types based on layer or colour of the input contours.

◦ When one CAD file contains geometry for multiple parts, all parts are loaded, without change in their mutual placement – as one multi-part. When one DXF file contains multiple AutoCAD blocks – particular parts are loaded.

◦ The measurement unit of the imported geometry can be selected during import.

◦ When the name of the file or the AutoCAD block contains quantities, the parts are imported automatically in the nesting job with those quantities.

• Parametric partsThe library contains a variety of parametric parts. Each part opens a draft and by inputting dimensions and parameters a new part can be created in Vintech RCAM-Pro.

Control

• ProjectVintech RCAM-Pro saves the data during the nesting process in a project file in a folder on the operating system.

The system supports all needed data in the project file in order to provide access to the project for both the user that has created it and for a remote user of the system.

• Nesting managementTo manage the design process the system uses Job, Nesting queue, Project navigator and Project tree. Each nested part can be

individually selected from the project tree, from the job or from the nesting queue.

Galleries are used for general access: for all layouts and plates – gallery Project, for all parts – gallery Parts, for all blocks – gallery Blocks.

• Plates for nesting in project

Vintech RCAM-Pro nests on whole blanks or usable remnants (UR). The plates are created with direct input of plate parameters, by selecting premade platesfrom PlaitsDataset or byimportinggeometry fromCAD file. A limitfor each platecan be defined.In a project it ispossible to nest on preliminary set plate dimensions. The system intelligently controls the multiplicity of the plate/nesting layout. It can trim and extend a plate at any time, define dangerous areas for clamps and calculate usable remnants with rectangular or free shape.

• Nesting layouts Variants

Vintech RCAM-Pro can exclude layouts from the project, after which they become unusable and their parts are returned for nesting. Vintech RCAM-Pro can lock layouts, after which they are

uneditable and their parts are not returned for nesting. Reports and NC programs can be generated for the locked and excluded layouts.

• Interactive nesting toolsAround the selected for interactive nesting objects, the system places “handles” of

functions for nesting: continuous and step-by-step rotation, mirroring, control of nesting in a pattern, automatic attraction and dynamic reorientation, common cut nesting.

• Creating technology at any timeDistinctive characteristic of Vintech RCAM-Pro is that the Processing technology for the whole layout or for a part of it can be created or removed at any time . It is possible to nest partswithout creating technology and then to create the Cutting technology before generating the NC program. It is also possible to preliminarily create the technology for each part and to nest parts with that technology.

• Nesting

Vintech RCAM-Pro nests with high efficiency. It uses algorithms for tight step-by-step nesting and on-line control against overlapping, which does not allow nesting an object on top of already nested ones. The system has an extended functionality for automatic or interactive nesting. Vintech RCAM-Pro allows interruption of the automatic nesting, interactive action and resumption of the automatic nesting, at any moment.

• Automatic tight nestingFor certain angular positions , the system optimises, finds place and orientation of a part or a block on the plate and then nests it tightly to the already nested objects. Automatic nesting is performed in the order, set in the nesting queue and with the quantities, set in the job, on top of a single or multiple plates, until the plate limit or the parts in the job are expended.

• Unlimited insertion Vintech RCAM-Pro nests parts in a hole of another part. When there is free space for nesting a part on the plate and in a hole, the system will choose to nest in the hole. The levels of insertion are unlimited. Nesting in all holes or only in small holes can be forbidden from the settings.

• Flexible interactive nestingIn interactive mode the nesting can be with true shape or in a pattern, controlled by the “handles”.

The objects that are already nested or still waiting in queue for nesting, can be chosen for interactive nesting. Using the cursor they can be dragged, pushed or manipulated until they come close to the desired position on the plate.After dropping them, the algorithms for on-line control against overlapping, nest them tightly tothe already nested objects on the plate.

• Special methods for nestingVintech RCAM-Pro provides functions which takeinto account the characteristics of the CNC machines like: nesting on the edge of the plate; common cut nesting; parallel nesting with fixed spacing between the cutters and additional nesting after the parallel nesting; parallel nesting with variable spacing and cutters count .

• Working with blocks

Vintech RCAM-Pro includes a large number of functions for working with groups of nested parts, with or without technology, called blocks.

Blocks can be used as they have been created or they can be broken and finished on the spot. Blocks are used everywhere in the system.

Technology• Cutting paths and route of rapid moves

Vintech RCAM-Pro provides unique tools for paths and route control.

◦ Cutting path is the path of the jet, which walks on a separate contour from a part in a way, set from the Processing technology. Vintech RCAM-Pro knows which contours are outer, inner, holes, slits, which paths are marked (or engraved), and also which points are for centring. The system creates paths automatically or interactively, with on-line control against overlapping, in correspondence with material, thickness, contours' type and length.

◦ Route of Rapid moves is the order of the processing of separate paths in a part and in a nesting layout.

• Automatic and interactive creation of paths

Vintech RCAM-Pro uses the information from theTechnological Datasets in order to create paths. The system finds space for the path elements, so that they do not overlap neighbouring objects, using the on-line control against overlapping. It creates:

◦ Start/End points; Gaps; Loops and sharp corner operations,

◦ paths with control of speed and acceleration in corners (with or without small radius),

◦ paths for marking and engraving,

◦ path for accurate plasma cutting of holes, when the plasma source allows turn-off control.

◦ chain cutting with circumventing

• Interactive creation of paths

◦ common cuts,

◦ cutting with bridges, including corner bridges and negative bridges,

◦ paths of parts nested on the edge of the plate,

◦ paths with “buttonholes” for Lead-In from neighboring path

◦ “L-locks” on the path

◦ pseudo-bridges with leading line, including on top of common cuts,

• Interactive editingChanges the place of Start/End point or Gap by dragging along the path, edits the slope and length of Lead-In and Lead-Out by dragging the relevant „handles“, changes the type of Lead-In/Out using „halos“.

• Creation of routeVintech RCAM-Pro provides advanced features

◦ Maintaining powerful functions for transfer of NC programs between different types of machines.Vintech RCAM-Pro allows automatic change ofmachine, cutting regime, technology, kerf and post-processor in the project at any time.

• Automatically and interactively solve special tasks for true shape nesting, such as:

◦ Common cuts: by pairs, in matrix of rectangular parts, in multitudes of variable parts,

◦ collision limiting, by reorientation of Start/End points according to the order of contour processing,

◦ creating nesting layouts with continuous cutting and lead-in from the edge of the plate,

◦ technologies for processing by frames (withrepositioning) for plates longer than the work stroke of the machine,

◦ slicing the scrap skeleton,

◦ cutting of gaps after the main processing,

◦ transformation of rapid moves into cutting paths for chain cutting with circumventing.

• Generate reports and documents

◦ Creates HTML, PDF and DXF documents for a snigle layout or all layouts in the project.
