摘要
针对常规手工编程中难以加工非圆二次旋转曲线的问题,对华中数控系统中典型的非圆二次函数公式曲线轮廓的车削加工进行研究。首先根据加工轮廓确定中心在坐标原点,且不倾斜的曲线方程,在solidworks软件中创建表达式,应用规律曲线参数模块绘制出曲线图形;然后将表达式中的方程进行坐标旋转及平移转换,绘制出与加工图纸一致的曲线轮廓;最后采用分析归纳法得出二次旋转曲线的宏程序模块,并给出该宏程序在旋转双曲线和椭圆曲面零件加工中的编程应用。实践表明,该宏程序对数控编程基础人员灵活应用非圆二次旋转曲线轮廓的编程方法与技巧有实际的指导意义。
It is difficult to process Non-round conic hyperbola curve in conventional manual programming,now,studying turning of Non-round conic hyperbola outliner on HNC-21T numerical control system.First,acts according to the processing outline determination center in the origin of coordinates,founds the expression of non-incline equation of a cure by the solidworks software,and draws up the curvilinear figure based on the application rule curve parameter module,then carries on the expression in equation coordinates revolving and the translation transforms,draws up with the processing blueprint consistent curve outline,the general macro of Non-round conic hyperbolic is obtained in analysis and induction,and is applicated in Revolving hyperbolic curve processing parts.Processing practices prove： it is significant to improve programming methods and techniques for the certain person who has the basis of NC programming.
