基于CATIA特征识别的数控车快速编程技术

Research on NC Turning Programming Highly Efficient Based on Feature Recognition of CATIA

通过基于CAA的Catia二次开发,从Catia中提取零件回转特征,并自动匹配加工参数库,从CAD数模直接生成数控车NC程序,实现快速、简便地编制出优质数控车程序。针对提取的CATIA特征具有多种不确定性,提出车削特征轮廓的分离整理技术,解决了零件外圆内孔线条分离及轮廓线条排序等问题。

For making the high quality and efficiency NC program fast,firstly,obtain the turning features in Catia model based on CAA,and then match the cut parameter database,lastly,generate the turning NC program from CAD model immediately.During this process,propose a separate-arrange technology for solving these problems of separating lines of hole and outline,and sorting and so on.
