TECH. CAD- CAM EXPERIMENT NO : 1AIM: TO STUDY INTRODUCTION MANUFACTURING. CIM DEFINATION:Computer Integrated Manufacturing, known as CIM, is the phrase used to describe the complete automation of a manufacturing plant, with all processes functioning under computer control and digital information tying them together. Computer-integrated manufacturing (CIM) may be viewed as the successor technology which links computer-aided design (CAD), computer-aided manufacturing (CAM), robotics, numerically controlled machine tools (NCMT), automatic storage and retrieval systems (AS/RS), flexible manufacturing systems (FMS), and other computer-based manufacturing technology. Computer-integrated manufacturing is also known as integrated computer-aided manufacturing (ICAM). Auto factoring includes computer-integrated manufacturing, but also includes conventional machinery, human operators, and their relationships within a total system.TO</p> <p>DATE: ..../..../........COMPUTER INTEGRATED</p> <p>EVOLUTION OF CIM:Manufacturing industries have evolved tremendously from cottage industries in the early 16th century to the global force as it stands today. The characteristics of the present world market include higher competition, shorter product life cycles. Greater product diversity, fragmented markets, variety and complexity and smaller hatch sizes to satisfy a variety of customer profiles . Furthermore, non-price factors, such as quality, product design, innovation and delivery services are the primary determinants of product success in today's global arena . To achieve these requirements, manufacturing companies need to be flexible. adaptable.</p> <p>1</p> <p>Computer Integrated Manufacturing</p> <p>responsive to changes, proactive and be able to produce variety of products in a short time at a lower cost in addition, they should be able to address new environmental requirements, complex social issues and concerns. Hence, manufacturing companies are compelled to seek advanced technologies as a panacea for all these needs. The most significant outcome of this search resulted in the concept of computer integrated manufacturing (ClM) in the early 1970s. The concept of ClM was initially coined by Dr. Joseph Harrington in 1973 in the book "Computer Integrated manufacturing". However, until the early 1980s, CIM did not become a commonly known acronym as it exists today. The idea of "Digital Manufacturing is a vision for the 1980s. In the 1980s, Computer Integrated Manufacturing was developed and promoted by machine tool manufacturers and the CASA/SME (Computer and Automated Systems Association /Society for Manufacturing Engineers).</p> <p>CIM HARDWARE:CIM hardware includes all the devices which are having physical presence. All the devices which we can see, touch, can operate with application of human effort is known as a hardware, in case of CIM all the applications accept programs are hardware. Majorly we can classify them in this m/c tool format.</p> <p>CIM Hardware2</p> <p>Computer Integrated Manufacturing</p> <p>Manufacturing equipment such as machines or computerized work centers, Robotic work cells, DNC/FMS systems, VNC systems, Work handling &amp;tool handling devices, Inspection machines etc Computers ,controllers ,CAD/CAM systems ,work stations/terminals, Data entry terminals, Bar code readers, Printers ,plotters and other peripheral devices, modems ,cables ,connectors etc.</p> <p>CIM SOFTWARE:CIM software is combination of following function software: MIS (management information system): MIS software helps for managing your accounts, inventory, taxation, payroll, stock, banking, financial and other records. MIS involves all aspects of gathering, storing, tracking, retrieving and using information within a business or organization. All the policies, procedures, and practices that direct an organization's operations and the staff that interact with the information, combined with the software and hardware, comprise an information system. PLANNING AND SCHEDULING: It delivers a single database that contains all data for the software modules, which would include: Manufacturing: Engineering, bills of material, scheduling, capacity, workflow management, quality control, cost management, manufacturing process, manufacturing projects, manufacturing flow Supply chain management: Order to cash, inventory, order entry, purchasing, product configuration, supply chain planning, supplier scheduling, inspection of goods, claim processing, commission calculation Financials: General ledger, cash management, accounts payable, accounts receivable, fixed assets Project management: Costing, billing, time and expense, performance units, activity management Human resources :3</p> <p>Computer Integrated Manufacturing</p> <p>Human resources, payroll, training, time and attendance, roistering, benefits Customer relationship management: Sales and marketing, commissions, service, customer contact and call center support. Data warehouse and various self-service interfaces for customers, suppliers, and employees Access control - user privilege as per authority levels for process execution Customization - to meet the extension, addition, change in process flow. COMPUTER AIDED DESIGN: (CAD) Computer-aided design software is the use of computer technology for the design of objects, real or virtual. The design of geometric models for object shapes. Phesibility of design, testing as per software programs based on practical observations. Static, kinetic and dynamic analysis of design. COMMUNICATION: Communication software is used to provide remote access to systems and exchange files and real-time messages in text, audio and/or video formats between different computers. This includes terminal emulators, file transfer programs, chat and instant messaging programs, as well as similar functionality integrated within MUDs(multi-user dungeon).This is for creating proper communication between person to person, person to machine, machine to machine, machine to person.. OFFICE AUTOMATION: Office Automation software is very beneficial to the company having big kind of business for export and import. This Office Automation software is the easier way to store details of the multiple company (you own) or working with. The Office Automation software can be used any time and you can store as many data as you want to. Office Automation software will keep record of all the things that is entered by you.</p> <p>MAJOR AREAS OF CIM:Areas Of CIM includes major four areas which are having their own parts which we can include with them:</p> <p>4</p> <p>Computer Integrated Manufacturing</p> <p>PRODUCTION MANAGEMENT SYSTEM: Management information system, Sales Marketing, Finance, Database management, Communication, Network management. DESIGN AND MANUFACTURING SUPPORT SYSTEM: Modeling and Design, Simulation, Analysis, Manufacturing area control Process Planning, Manufacturing facilities, Quality management. MACHINE TOOLS: Work flow automation, driving devices MATERIAL HANDLING SYSTEM: Ordeal entry, Job ticketing, Material storage units, etc.</p> <p>ELEMENTS OF CIM:We can say that there are basically nine major elements of CIM system: Marketing: The need for a product is defined by the marketing division. The specifications of the product, the projection of manufacturing quantities and the strategy for marketing the product are also decided by the marketing dept. Product Design: The design department of the company establishes the initial database for the production of a proposed product. In CIM system this is accomplished through activities such as geometric modeling and computer aided design while considering the product requirement and concept generated by the creativity of the design engineer.</p> <p>5</p> <p>Computer Integrated Manufacturing</p> <p>Planning: The planning department takes the database established by the product design and enriches it with production data and information to produce a plan for the production of product. Purchase: The purchase department is responsible for placing the purchase orders and follows up, receives the item, arrange for inspection and supply the items to store for eventual supply to manufacture and assembly. Manufacturing Engineering: Manufacturing Engineering is activity of carrying out the production of the product, involving further enrichment of the database with performance data and information about the production equipment and processes. Factory Automation Hardware: Factory automation equipment further enriches the database with equipment and process data, resident either in the operator or the equipment to carry out the production process. Warehousing: Ware housing is the function involving storage and retrieval of raw material, components, finished goods as well as shipment items. Finance: Finance deals with the resource pertaining to money. Planning of investment ,working capital, cash flow control, accounting, and allocation of funds are the major task of finance department. Information Management: It is perhaps one of the crucial tasks in CIM.This involves master production schedule, database management, communication, manufacturing system integration and management information systems. Which can be directly understand by figure</p> <p>6</p> <p>Computer Integrated Manufacturing</p> <p>ACTIVITIES OF CIM:CIM Technology ties together all the manufacturing related functions in a company:</p> <p>Activities of CIM</p> <p>Cad,Shopdata,FEM,MEM,Analysis,Drafting,Processplanning,ToolDesign,Scheduling ,Si-mulation,CNC,Robots,FMS,AS/RS,QC. Marketing, Finance, Purchase, Human Resource, ERP, Shipping, Database.</p> <p>7</p> <p>Computer Integrated Manufacturing</p> <p>Machine Tool ,Material Handling system ,Computer system ,FEM ,Element Modeling ,MEM,ERP(Enterprise Resource Planning) ,QC.</p> <p>KEY CHALLENGES:There are three major challenges to development of a smoothly operating Computer Integrated Manufacturing system: Integration of components from different suppliers: When different machines, such as CNC, conveyors and robots, are using different communications protocols. In the case of AGVs, even differing lengths of time for charging the batteries may cause problems. Data integrity: Data integrity is a term used in computer science and telecommunications that can mean ensuring data is "whole" or complete the condition in which data are identically maintained during any operation, the preservation of data for their intended use, or, relative to specified operations, and the prior expectation of data quality. : The higher the degree of automation, the more critical is the integrity of the data used to control the machines. While the CIM system saves on labor of operating the machines, it requires extra human labor in ensuring that there are proper safeguards for the data signals that are used to control the machines. Process control: Process control is a statistics and engineering discipline that deals with architectures, Mechanism s, and algorithms for controlling the output of a specific process.... Computers may be used to assist the human operators of the manufacturing facility, but there must always be a competent engineer on hand to handle circumstances which could not be foreseen by the designers of the control software.</p> <p>8</p> <p>Computer Integrated Manufacturing</p> <p>Set up time, Quality, Manufacturing, Inventory, Flexibility, and Distance. Manufacturing industry Goals. Market position, Global economy, etc</p> <p>CIM WHEELS:CASA/SME (Computer and automated system association of society of manufacturing Engineers) has suggested a framework, the CIM WHEEL to explain the meaning of CIM. CIM is a closed loop system whose prime inputs are product requiring concept prime output are finished product. CIM WHEEL depicts a central core (Integrated System Architecture) That handles the common manufacturing data and is concern with information resources management and communication. The radial sectors surrounding the core represent the various activities of manufacturing processing design, material, processing and inspection. This activity has been grouped under three categories. Manufacturing planning and control, Product process, Factory Automation The outer rim represents the upper management functions, grouped into four categories: Strategic Planning Marketing Manufacturing and HRManagement The modifications have been done by researchers for making the CIM WHEEL acceptable in all industries as per requirements.</p> <p>Key Strengths: CIM creates a database of information.</p> <p>9</p> <p>Computer Integrated Manufacturing</p> <p>CIM Can be applied to other sectors. CIM is low cost, low effort to get started. Manufacturing Planning and Scheduling is possible. Easy to understand islands of the CIM. Resource allocation is easier than conventional method.</p> <p>Key Weaknesses: No compelling reason for growers to participate. Needs on-the-ground (arms-&amp;-legs) facilitation. It cannot show complete connection between different island of CIM. No clear instructions are there for implementation. It do not have time constrain so may take months for implementation.</p> <p>Declared by CASA/SME in 1980, 1985, 1986.
