零件的分类编码是成组技术的基础。在组成零件族,建立加工组以后,即可着手生产工艺准备工作。诸如编制成组工艺规程、设计成组机床夹具、组建生产单元等等。编制成组工艺规程的目的,是建立一种与单件工艺规程差别不大,足以供某一族零件遵循的加工工艺。 Part classification coding is the basis of group technology. In the composition of parts family, the establishment of processing group, you can proceed with the production process preparation. Such as the preparation of a group process rules, the design into a group of machine fixtures, set up production units and so on. The purpose of preparing a group of rules is to establish a process with little difference between single, enough for a family of parts to follow the processing technology.
