理、机械设计中的课程设计整合，构建了独立的综合性课程 —— 机械基础课程设计； ③ 新开出三个实践环节，即机械制造技术课程设计（ CAPP）、微机原理及接口技术课程 设计和数控加工综合实践。 如数控加工实践环节，要求学生在一周内以 3～ 5 人为一组，针对一个零件在计算机上编制加工程序，然后通过网络将程序传送到数控加工中心加工成零件； ④ 传统的金工实习时间由 6 周减少至 4 周； ⑤
cisely the key factors in improving the efficiency. The methodology of case based reasoning (CBR) adapts the solution of a previously solved case to build a solution for a new problem with the
t for the deep drawing process: excessive speeds can cause wrinkling or fracture in the formed part and damage of the tooling: while insufficient speeds reduce the rate of production. In this
The pressed air supplied to the collector of the shot blast equipment is dried by an oil moisture separator. However, this method of drying is inadequate. Water vapor condenses in the main line and
