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。
For parabola and other regular curve processing need to use macros to achieve, but there is no ready-made instructions can be called. Based on FANUC numerical control system analysis and summary of various types of parabolic processing macro program, and then designed a generic parabolic macro program. The rough finishing is separately researched and designed. By using the FANUC macro G code calling function, the G101 parabola interpolation function instruction is developed. Through the built-in general macro program, the repetitive macro program editing in different parabolic processing is simplified. Processing only need to use the command G101 and according to the processing conditions specify the relevant parameters to complete the processing, the processing of the parabola is similar to the arc as easy, greatly simplifying the programming, especially for regular curve processing occasions can be effectively increased Programming and processing efficiency.
