为了提高变型零件的数控编程效率和品质,提出了对零件族数控程序母模板进行克隆和变异,使其快速派生出变型零件数控程序的编程方法。首先分析了数控程序母模板能被克隆和变异的必需条件,然后以母模型零件加工特征为数控加工单元进行几何数据的提取和加工参数的设置,构建了零件族数控程序母模板,并给出了由数控程序母模板克隆和变异出变型零件数控程序的方法和流程。最后以实例验证了该方法的可行性。

To improve quality and efficiency of Numerical Control （NC） programming of variant parts . a rapid programming method based on clone and variation of the master template of the NC program by was proposed. First, the necessary conditions of the master template that could be cloned and variation were analyzed. Then, geometric data of machining features were extracted and process parameters were set up. The master template of NC program was constructed by according machining feature as unit of NC information. Methods and processes of variant parts CNC program by the master template of the NC program cloning and mutation were given. Finally, an example was applied to verify the feasibility of this method.
