CNC软件圆弧插补算法的分析与研究

THE ANALYSIS AND RESEARCH OF CTRCTTT.AR INTERPOLATION METHODS FOR CNC SOFTWARE SYSTEM

快速而准确的圆弧插补算法一直是人们努力追求的目标。本文在深入分析了五种圆弧插补算法的基础上,把它们归纳到统一的理论依据之下,并就人们在理论方面研究甚少的插补运算的速度和插补轨迹精度问题进行了深入的分析与理论推导。同时,通过在计算机上对各种插补算法在插补运算速度和插补轨迹精度两方面的实际测试、验证与分析比较,提出了最佳择优方案,并在实际应用之中取得了满意的效果。

A kind of circular interpolation method with speed and accuracy is a goal to be seeked for. On the basis of analyzing five interpolation methods,they are concluded under the same theroical basis. Moreover,these interpolation methods are analyzed and studied Throughly in terms of accuracy and speed, through practical test verification and compasison,selection of the appropriate method is found. In practical use,a satisfaction is also abtained.
