1、英语原文：CAD/CAM is the technical expression, indicates the computer-aided design and the computer aided manufacturing.This is one item in the design and the production, carries out certain function technology about the use computer data.This technology is completing the design and the production direct
2、ion to the place develops.In these two traditions was considered is in the production process out of the ordinary, independent function.In brief, CAD/CAM will be able to provide the technology base for the future complete computer production.Looked from the computer science angle that, the design an
3、d the manufacture process is one has, processing, the exchange and the management process about the product information.The people use the computer to take the main technical method, from forms in ones mind to the product to put in the market in the entire process information to carry on the analysi
4、s and processing, produces and utilizes each kind of numerical information and the graph information, carries on the product the design and the manufacture.The CAD/CAM technology is not the traditional design, the manufacture flow method simple reflection, also is not limits in the partial use compu
5、ter takes the tool in the individual step or the link, but is unifies the computer science and the project domain specialized technology as well as humans wisdom and the experience take the modern scientific method as the instruction, in the design, in the manufacture entire process each completely
6、manager, as far as possible use computer system completes the work which these duplication high, the labor big, the computation complex as well as depends on purely artificially completes with difficulty, but assists must replaces the engineers and technicians to complete the entire process, obtains
7、 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 computation, the analysis, optimized, the cartography, the technological process design, the simulation as
8、 well as the NC processing.But the generalized CAD/CAM integrative system also should include aspects and so on production plan, management, quality control.Since 1946 first electronic accounting machine has been born in US, people on unceasing computer technology Introduces the machine design? Manu
9、facture domain.As early as in the 50s, for the first time develops successfully the numerical control engine bed, may realize through the different numerical control procedure to the different components processingAfterwards, Massachusetts Institute of Technologys servo laboratory succeeds with the
10、computer manufacture numerical control paper tape, has realized the NC programming automation.In this foundation, the people proposed the following tentative plan: The APT software is feeds the path method realization computer assistance programming through the description, that, can not describe fe
11、eds the path, but is direct description components itself? From this has had the CAD initial concept.The entire 50s, the electronic accounting machine also is in the electron tube time, uses the machine language programming, the computer mainly uses in the science computation, also only has the outp
