Application Research of the Macro Program in Linear Variable Radius Fillet Surface Milling

线性变半径圆角曲面在复杂类零件中应用较广,通过运用数学知识对刀位点进行数值计算,利用宏程序编写数控程序代码,能够使数控机床快速、准确的实现自动加工。采用通用的FANUC 0i mate-MC数控系统,完成了线性变半径圆角曲面宏程序编制,在宏程序起始段赋予正确的数据到相应的变量,能够准确地控制球刀刀位点的运行轨迹,确保线性变半径圆角曲面加工精度达到要求。

Linear variable radius fillet surface in complex parts have been widely used in practice. It can be made accurately on numerical control machine tools,which has been programming with the application of macro instruction before computing cutter position point coordinate figures with mathematical knowledge. Using a common FANUC 0i mate-MC CNC system,programmer has completed macro programming about the linear variable radius fillet surface. Giving the correct data in the initial segments of the corresponding macro variables,the CNC machine tools can accurately control the trajectory of ball-end cutter center,and ensure linear variable radius fillet surface machining accuracy requirements.
