【摘要】 首先分析了派生式CAPP系统设计采用生产流程分析法(PFA)对零件分组的必要性;详细介绍了基于PFA的派生式简易CAPP系统的设计过程,包括对零件编码、分组、建立特征矩阵及工艺文件等.使用该系统为每个零件编制工艺规程时,只需对标准工艺规程作少量修改,同时还可得到加工所用的机床组,极大地提高了工艺部门的工作效率.更多还原

【Abstract】 The design of variant CAPP system using PFA to group parts is necessary.The process of the design is introduced,which includes part encoding,grouping,establishing characteristic matrices and technology file.When the process of each part is planed using this system,the standard technology process is modified only a little.At the same time the work machine group is gotten.This brings high work efficiency to technology department.更多还原
