离散逼近非圆曲线之宏程序研究
摘要: 实际生产中对非圆曲线常常釆用离散逼近的方法加工,其编程主要有CAD/CAM自动编程和手工编程,作为手工编程的代表数控宏程序有着较突出的优点,基于国内数控宏程序研究和应用的现状,本文总结和比较了各类离散逼近非圆曲线的加工方法的优缺点,总结了各种逼近方法的数控宏程序,提出了等间距直线逼近法步距的校核方法,对等误差直线逼近法重新建立了数学模型,简化了程序,在一定程度上实现了各类离散逼近方法的纯手工编程.
关键词：非圆曲线；数控宏程序；手工编程; 离散逼近

The study of macro programme for discrete approximation of non-circular curve
Abstract: The discrete approximation is the method often used to process the non-circular curve in the actual production. There are mainly two programming ways, CAD/CAM auto-programming and manual programming. Digital macro programme that is a representative of manual programming, has some very prominent advantages. According to the study and current applicational situation of the domestic digital macro programme, this paper summarizes and compares the advantages and disadvantages for the various kinds of processing methods for discrete approximation of non-circular curve, summarizes the macro programmes for many kinds of approximation, raises the inspection method of equal-spaced straight line approximation step distance, reestablish the mathematical model for equal-error straight line approximation method, simplifies the programme and implements the pure manual programming of all kinds of discrete approximation methods to a certain extent.
Key words: non-circular curve, digital macro programme, manual programming, discrete approximation
