机械CAD技术的发展(综述)

对ＣＡＤ（计算机辅助设计）的发展过程、趋势进行了综述，认为ＣＡＤ技术从５０年代起始，已经历了４个发展阶段，进入了当今的迅速普及时期，出现了集成化、智能化、标准化和实用化的发展趋势。我国在“九五”期间将大力推进ＣＡＤ技术，到２０００年，主要行业ＣＡＤ技术的普及率和覆盖率将达到７０％以上，并应大力加强ＣＡＤ人才培养工作。

THE DEVELOPMENT OF CAD TECHNOLOGY ON MECHINERY(ABSTRACT)

There have been four processes in the development of CAD(Computer Aided Design) since it was studied in the fifties of 20th century and it has entered the period of being popularized quickly.Its prospect was good for integration,intelligence,standardization and practicability.It was during the last 5 years of this century that a decision was reached that we must strength the development of CAD.In the beginning of next century,the using on CAD in the main work will be over 70% and we must make certain efforts to train students to improve their ability to master the CAD.
