就我国的情况看来,除了必须设计一批产品单一的大量生产的工厂作为工业的骨干外,更多的是设计多品种的、小批或中批的工厂。因此,在设计时不可能对所有产品逐一分析,只能选定几种代表产品进行工艺设计。几年来在设计中选定代表产品进行工艺分析的方法有如下三种:(1)设计时对代表产品内每一名称零件进行详细的工艺分析,拟订出类似生产用的加工过程卡片,据此
As far as China is concerned, apart from having to design a single batch of products with a single mass-produced factory as the backbone of the industry, it is more to design a multi-variety, small-lot or medium-lot factory. Therefore, it is not possible to analyze all products one by one at the time of design, and only a few representative products can be selected for process design. In the past few years, the following three methods have been used to designate representative products for process analysis in the design: (1) A detailed process analysis is performed on each part of the representative product at the time of design, and a process card similar to production is drawn up.
