机械制造工艺设计是机械行业的一项经常性技术工作 ,设计中要求综合考虑加工质量、生产率和经济性的影响。但在实际工作中 ,很多技术人员片面强调加工质量、生产率 ,忽略了经济性 ,导致设计出的工艺方案加工质量很好 ,生产率很高 ,但经济效益却很差的状况。因此有必要强调一下 Mechanical manufacturing process design is a regular technical task in the machinery industry. The design requires comprehensive consideration of the effects of process quality, productivity, and economy. However, in actual work, many technicians emphasize the processing quality and productivity, ignoring the economy, resulting in a good process quality of the designed process, high productivity, but poor economic efficiency. Therefore it is necessary to emphasize
