摘要
文章以数控系统中的刀具半径补偿算法作为研究对象。采用了对刀具半径补偿算法进行数学建模的方法,根据计算得出的加工曲线衔接处方向矢量差值的分布区间特征来判断需要使用的刀具半径补偿算法类型,进而给出并论证了"交点过渡法"刀具补偿算法的补偿类型判据,实现了"交点过渡法"刀具补偿算法。目前阶段通过在机床上实际运行得出的结果表明:"交点过渡法"在高速铣削加工中具有补偿曲线平滑、补偿点计算精确、加工表面质量好等优点。
The study subject of this paper is the algorithm in numerical control system. This paper presents work on the algorithm in numerical system. Using the methodology of modeling via the algorithm, this paper demonstrates the criteria of compensation type on the basis of the calculations of to discriminate the required typ e of the algorithm, and enabling the algorithm. The outcome of practical application on the machine also reveals the advantages of this method in high speed milling smooth compensation curve, accurate compensation point calculation and good quality of surface machining.
