数控加工主要适用于批量生产的形状复杂零件,其尺寸精度和几何位置精度要求高度一致性,这就要求数控程序优化,既耗时又繁琐。而宏程序一次编程,所有与该宏程序所表述的相同几何形状的结构,不管尺寸是否一致,只要按要求的变量进行赋值,就可以调用该宏程序,比普通编程效率高又准确。 CNC machining is mainly applied to the production of complex parts of complex shapes, the dimensional accuracy and geometric accuracy of the location of a high degree of consistency, which requires CNC program optimization, both time-consuming and cumbersome. The macro programming, all the procedures described with the macro geometry of the same structure, regardless of the size is consistent, as long as the required variables for assignment, you can call the macro program, higher than normal programming accuracy and accuracy.
