宏程序指令在非圆曲线数控加工中的应用

Application of Macro Program Instruction in NC Machining of Non-circular Curve

介绍了宏程序的概念、宏程序的优势及宏程序在非圆曲线数控加工中的应用。结合宏程序,运用数学编程方法设计椭圆、双曲线等非圆曲线的数控加工程序,应用简单、便捷,可保证粗、精加工精度,有较强的适用性和通用性。

This paper introduces the concept of macro program,the advantages of macro program and its application in non-circular de-curve NC machining.Combined with the macro program,the mathematical programming method is used to design the NC machining program of non-circular curves such as ellipse and hyperbola.The application is simple and convenient,can ensure the precision of rough and fine machining,and has strong applicability and versatility.
