Group process and the preparation process of CAPP
in order of Abstract : introduced a group of GT (Group Technology) and CAPP (Computer

Aided Process Planning) of the basic method. proposed PDM (Product Data Management) system

as the Integrated Framework, there will be the traditional application software for

AutoCAD and CAPP organically integrated, make CAPP software development platform tends

unified direction.

 Group Technology
Group of the so-called Group of GT (Group Technology) is to a wide variety of single

pieces of small batch production of parts, according to its shape structure, technical

requirements and processing methods are similar, turning parts into several groups, In

each group parts elect a representative parts (it is real and it can also be imagined,

However, within the group must include all parts of the processing elements), according to

the representative of a typical parts of the development process in order and selected

group and design a machine and process equipment, and they formed a special workshop or

Section. When processing an object by changing parts of the same group when the other

parts, Due to technical requirements,

成组工艺和CAPP 在编制工艺规程中的应用
摘　要: 介绍了成组工艺GT( Group Technology) 和CAPP (Computer Aided Process Planning) 的基

本方法. 提出以PDM( Product Data Management) 系统作为集成框架,将已有的传统应用软件AutoCAD

和CAPP 进行有机地集成,使CAPP 软件的开发平台趋向统一的发展方向.

　                      成组工艺
　　所谓成组工艺GT( Group Technology) ,就是把品种繁多的各种单件小批量生产的零件,根据其外形

结构、技术要求和加工方法的相似性,把零件分成若干组,在每一组零件中选出一个代表零件(它可以是

实际存在的,也可以是假想的,但必须包括组内所有零件的加工要素) ,根据这个代表零件制定一套典型

的工艺规程,选定和设计一组机床及工艺设备,并把它们组成一个专门的工段或车间. 当加工对象由一种

零件转变为同组内另一种零件时,由于技术要求、结构和工艺的相似,可以不改变加工方法和加工设备,

甚至连控制用的凸轮、挡铁以及工、夹具都不更换,或者只需略作调整,便可进行加工生产. 例如,运用
