文档介绍：puter Aided Manufacturing
Today’s petes in a truly international marketplace. Efficient works have created a “world market” in which we participate on a daily basis. For any industrial country pete in this market, it must panies that provide economic high-quality products to their customers in a timely manner. The importance of integrating product design and process design to achieve a design for production system cannot be overemphasized. However, even once a design is finalized, manufacturing industries must be willing to modate their customers by allowing last-minute engineering-design changes without affecting shipping schedules or altering product quality.
Most .-based panies look toward CAD/CAM and CIM to provide this flexibility in their manufacturing system . Today ,the use puters in manufacturing mon . Manufacturing system are being designed that not only process parts automatically ,but also move the parts from machine to machine and sequence the ordering of operations in the system.( Figure 1) contains a plot of the economic regions of manufacturing. It should be noted that manual handcrafted goods will always have a market in the United States as well as abroad. This is also true of industrial products—there will continue to be a need for special one-of-a-kind items. The spectrum of one-of-a-kind goods through high-volume goods dictates that a variety of manufacturing methods be used to meet our various industrial needs. Some of these systems will look like the factories that our grandparents labored in, whereas others will take on a futuristic look. In the following sections, a discussion of flexible manufacturing systems is presented.

MANUFACTURING SYSTEMS
A flexible manufacturing system, or FMS as they are monly known, is a reprogram-able manufacturing system capable of producing a variety of products automatically. Since Henry Ford first introduced an
