八方向进给的目标跟踪插补法

Method of Object Tracking in Eight Directions to Feed and Interpolate

介绍一种采用目标跟踪的插补运算,在电火花线切割机上实现八方向进给插补控制的数学模型,与常用的逐点比较法插补运算进行比较,目标跟踪法具有运算公式简单、速度快、程序短和进给速度稳定等特点.此外还介绍了目标点跟踪插补运算的框图及软件设计方法.

This paper deals with a mathematical model in which the control of the electrical discharge wire - cutting machine through feeding and interpolating in eight directions is implemented based on the principle of object tracking with interpolation. A comparative study between this method and the point -by - point comparison with interpolation proves that it has some traits： simple formula, fast velocity, short program and stabilization of feeding and interpolating velocity. Furthermore, the block diagram and the software design in the interpolation method by object tracking are presented.
