摘　　要：一般刀具轨迹生成算法存在某些明显不足,如刀位点过多、轨迹均由直线段构成等,使用中不仅不便于管理,还可能引起刀具与机床的机械冲击。作者提出用增量优化算法解决刀具轨迹的优化问题,目的是精简冗余刀位点,并对刀具轨迹进行光顺处理,以减小对数控机床的机械冲击。算法的特点是通过控制增量因子,在精度允许范围内改善原轨迹的光顺性,获得最佳优化效果。Tool-path generated from traditional methods often contains a lot of redundant cutter location points and too many short lines, causing inconvenience in data management and extraordinary motion of cutter which may cause concussion between cutter and machine tool. An incremental refining algorithm is presented to reduce the cutter location points and make the tool-path more smoothly. The essence of the new algorithm is to gain the better smooth performance by controlling the incremental factor following the precise contour of work piece in context of the given tolerance.
