The quick turnaround cell – an integrated manufacturing cell with process planning capability

This paper investigates the information processing function of a computer-integrated manufacturing (CIM) system, which is usually neglected by engineers when they study the performance of a manufacturing system. The feasibility of developing a complete simulation model which would include both the operational and information processing functions is therefore considered. In order to achieve this, a typical pick-and-place manufacturing cell was considered in which 46 devices were connected to a local area network (LAN). Two independent simulation tools, SIMAN* and L-NET†, were used in order to develop the complete model. The model was evaluated and used to study the performance of the pick-and-place cell using different communication protocols such as the IEEE 802.3 carrier sense multiple access with collision detection (CSMA/CD), IEEE 802.4 token bus and the IEEE 802.5 token ring. Results presented in this paper show that with careful design and simulation it is possible to develop a complete model which includes both operational and informational processing functions. Although the example of the pick-and-place cell is relatively simple the technique adopted could be applied to any CIM system. Results have also shown that for the pick-and-place cell considered in this paper an IEEE 802.3 CSMA/CD protocol operating at 10 Mbps would guarantee access to the network within the shortest station processing time.

Abstract The conventional design to manufacture cycle time in producing a part can be reduced by eliminating design errors and difficult to machine features before process planning begins. This paper discusses the identification, development and operation of an approach which uses a data base of flexible manufacturing cell capabilities in order to analyze a design for manufacturability. Designs which the cell protocol is unable to produce are rejected, and ways in which a design may be made more producible are suggested to the user. This paper addresses issues, such as material availability, tool availability and the acheivability of tolerance, as they relate to the flexible manufacturing cell which contains a Matsuura 510V CNC machining center, a robot and simulated AGV and fixturing. An important contribution of this work, which is an integral part of the overall system protocol, is the wide variety of manufacturability constraints covered and the convenience of including it in the overall part design and process planning protocol.
