摘　　要：对于抛物线等规律曲线的加工需要用宏程序来实现,而没有现成的指令可以调用。基于FANUC数控系统分析总结了各类抛物线加工宏程序,进而设计了抛物线的通用宏程序。将粗精加工分别进行研究设计,运用FANUC宏程序G代码调用功能,开发了抛物线插补功能指令G101,通过内置通用宏程序简化了不同抛物线加工过程中的重复宏程序编辑。加工时只需运用指令G101并据加工条件指定相关参数值即可完成加工,使抛物线的加工类似于加工圆弧一样方便,大大简化了编程,尤其对于经常需要进行规律曲线加工的场合可以有效提高编程和加工效率。No ready-made instructions can call for processing of regular curve such as parabolic curve,so macroprogram should be designed.In this paper,we analyzed all kinds of macroprogram of the parabolic process based on FANUC numerical control system,to design a universal parabolic macroprogram.We separately studied roughing and finishing and used the calling function of G code of FANUC macroprogram to develope parabolic interpolation instructions of G101,to simplify macro repeat editor in different parabolic machining process through the preset of a universal macroprogram.The parabolic processing can be completed just by using the instruction of G101in combination with specifying related parameters according to processing conditions,and it becomes simple in processing an arc curve.The method can simplify the programming greatly,improve the programming and machining efficiency effectively,especially on the occasions that regular curve machining is often needed.
