【正文】 nicians to plete the entire process, obtains the desired effec The CAD/CAM system as well as plans the hardware, the software for supports the environment, (subsystem) realizes through each function module to the product description, the putation, the analysis, optimized, the cartography, the technological process design, the simulation as well as the NC the generalized CAD/CAM integrative system also should include aspects and so on production plan, management, quality 1946 first electronic accounting machine has been born in US, people on unceasing puter technology Introduces the machine design? Manufacture early as in the 50 s, for the first time develops successfully the numerical control engine bed, may realize through the different numerical control procedure to the different ponents processing Afterwards, Massachusetts Institute of Technology s servo laboratory succeeds with the puter manufacture numerical control paper tape, has realized the NC programming this foundation, the people proposed the following tentative plan: The APT software is feeds the path method realization puter assistance programming through the description, that, can not describe feeds the path, but is direct description ponents itself? From this has had the CAD initial entire 50 s, the electronic accounting machine also is in the electron tube time, uses the machine language programming, the puter mainly uses in the science putation, also only has the output function for it disposition graph system basic position CAD/CAM system hardware disposition CAD/CAM system software position CAD/CAM system software disposition Computer aided manufacturing (CAM) may define for uses the puter system to design, to manage and controls a productive plan the movement, through direct or indirect planned production resources puter contact defines states, the puter aided manufacturing application has 2 big aspects: 1) puter supervisory is the direct application, the puter with the production process connection, uses in supervising directly and the control production process 2) produces the support is the indirect application, middle the productive plan, the puter uses in supporting the production operation, but is not the puter and the production process links directly. Charting productive forces increase The CAD/CAM system may undertake the one whole set new charting theory to be able to strengthen the pletes next step, keeps firmly in mind the entire design to be possible to store up the the planner receives one with has saved the blueprint specification similar work piece, he only must recollect, and adjusts it the work storage place, revises in the original blueprint not to conform to a new work piece request part, productivity original work piece efficiency enhances, but this can enhance the next step working is a plete at times renewal database support, can facilitate the user to use Improve mapping analysis The charting analysis is another important work, it can by certain synthesize the CA
