使用数控机床在进行非圆曲线回转表面的加工时没有固定的G代码可以使用,给教学和生产带来了很多不便。文章结合工作实际,将椭圆曲线回转表面的加工利用参数化编程的方法加以实现,对于不同尺寸不同位置不同加工精度的零件只需要通过修改相应参数便可实现零件的加工,大大提高了此类零件的加工效率,具有一定的实用价值。 The use of CNC machine tools in the non-circular surface of the rotary processing of the surface without the G code can be used to the teaching and production has brought a lot of inconvenience. Combined with the actual work of the article, the elliptical curve of the surface processing using parametric programming method to be achieved for different sizes of different positions with different machining accuracy of the parts only need to modify the corresponding parameters can be achieved parts processing, greatly improving such parts The processing efficiency, has a certain practical value.
