摘　　要：数控高速加工时刀具轨迹必须满足刀具不能碰撞任何工件、卡具等要求,刀具轨迹变化不能过于剧烈,加工过程中引起的振动应在加工系统控制范围以内,进给速度能随着轨迹的曲率变化进行实时调整,切削深度尽可能均匀。本文从高速加工编程时的进退刀方式、移刀方式、走刀方式及刀具轨迹的拐角处理等4个方面进行分析研究,有效地优化刀具轨迹,提高了加工效率和工件加工质量。In numerical control high-speed machining, tool-track must meet the need of not collision with any workpiece and jig, the change of tool-track Should not be too drastic, the vibration caused in the processing system should be within the control of the processing system, feeding speed can be adjusted in real time and changed along with the curvature of the track, cutting depth, can be obtained in even as far as possible. In the high-speed machining programming ;the way of cutting feed, retreat, shift, and the corner dealing of cutting tool track were analyzed, thus the optimized track which improved processing efficiency and the quality of the workpiece machining.
