等槽宽变距螺纹加工宏程序编制

摘要

This paper analyzed the basic characteristics of pitch thread , the NC Macro program function and method of process control . Taken the specific variable pitch screw thread processing as an example , it discussed how to carry out the macro program of NC turning programming .%论文分析了变距螺纹的基本特征，阐述了数控宏程序的功能与流程控制方法，结合具体变距螺纹加工实例，探讨如何进行数控车削宏程序编写。
