摘　　要：提出一种新的刀具轨迹优化算法,使相邻加工轨迹间的残留高度值都等于允许残留高度值(规定精度),从而达到最大的切削带宽,消除了干涉。同时采用刀位显示验证方法对加工某叶片模型所得到的刀具轨迹进行验证。实验数据表明,在保证精度的前提下,轨迹数和轨迹长度明显减少,大大提高了多轴联动数控加工的效率。An pre-controlled optimal algorithm of tool-path arranging is presented. Because all the scallop height values between adjacent tool-paths are equal to the maximum allowance, maximal machining width can be obtained and gouge can be avoided. Then the tool-path of a manufactured blade model is verified by using display verification method. Experiment data shows that the number of tool- paths and the length of the whole tool-paths can be greatly reduced and multi-axis synchronous CNC machining efficiency is improved significantly while the accuracy is guaranteed.
