摘要
讨论了三点圆弧最大误差逼近曲线的算法,理论上使圆弧逼近的段数达到最少。基于Matlab进行了程序的编制求解节点,用等弦长等弧长的圆弧替代理论圆弧,搜索节点的初始值,保证了程序的可靠快速运行。圆弧连接光顺性较好,数控程序段数少、效率高。
Introduces the algorithm of three points are in maximum error approximating curve, theoretically making are approximated sections minimum. Based on Matlab nodes are solved through programming, and theoretical are is replaced by arc of equal chord and equal are length to search for initial value of node so as to ensure reliable and rapid running of the program. Arcs have smooth connections and numerical control program segments are less and efficient.
