Assembly involves the joining together of two or more separate parts to form new entity which may be assembly or subassembly. Automated assembly refers to the use of mechanized and automated devices to perform the various functions in an assembly line or cell. Automated assembly system performs a sequence of automated operations to combine multiple…
The two previous mechanisms convert a linear motion into a rotational motion. The Geneva mechanism uses a continuously rotating driver to index the table, as pictured in Figure 17. If the driven member has six slots for a six-station dial indexing machine, each turn of the driver will cause the table to advance one-sixth of…
An automated flow line consists of several machines or workstations which are linked together by work handling devices that transfer parts between the stations. The transfer of work parts occurs automatically, and the workstations carry out their specialized functions automatically. The flow line can be symbolized as shown in Figure1 using the symbols presented in…
For any of the three types of production, there are certain basic functions that must be carried out to convert raw materials into finished product. For a firm engaged in making discrete products, the functions are: 1. Processing 2. Assembly 3. Material handling and storage 4. Inspection and test 5. Control The first four of…
Another way of classifying production activity is according to the quantity of product made. In this classification, there are three types of production: 1. Job shop production 2. Batch production 3. Mass production 1.Job shop production. The distinguishing feature of job shop production is low volume. The manufacturing lot sizes are small, often one of…
Automation is a technology concerned with the application of mechanical, electronic, and computer-based systems to operate and control production. This technology includes: · Automatic machine tools to process parts · Automatic assembly machines · Industrial robots · Automatic material handling and storage systems · Automatic inspection systems for quality control · Feedback control and computer process control · Computer systems for planning,…
Joel Goldhar, Dean, Illinois Institute of Technology gives CIM as a computer system in which the peripherals are robots, machine tools and other processing equipment. Dan Appleton, President, DACOM, Inc. defines CIM is a management philosophy, not a turnkey product. Jack Conaway, CIM Marketing manager, DEC, defines CIM is nothing but a data management and…
Nine major elements of a CIM system are in Figure 2 they are, · Marketing · Product Design · Planning · Purchase · Manufacturing Engineering · Factory Automation Hardware · Warehousing · Logistics and Supply Chain Management · Finance · Information Management Figure 2 Major elements of CIM systems i. Marketing: The need for a product is identified by the marketing division. The specifications of…

Computers, controllers, CAD/CAM systems, workstations / terminals, data entry terminals, bar code readers, RFID tags, printers,…
Computer Integrated Manufacturing (CIM) is considered a natural evolution of the technology of CAD/CAM which by itself evolved by the integration of CAD and CAM. Massachusetts Institute of Technology (MIT, USA) is credited with pioneering the development in both CAD and CAM. The need to meet the design and manufacturing requirements of aerospace industries after…
