摘　　要：为了满足单转台四轴联动数控系统数控编程对空间刀具补偿的需要,提出一种空间刀具补偿向量模式的编程方法,并在这种方法的基础上改进了空间刀具补偿后置处理算法。该方法在自行研制的数控楼梯扶手弯头四轴联动机床上进行应用,取得了良好的加工效果。这种方法依托现有的CAM软件,具有一定的通用性,对开发带有空间刀具补偿功能的四轴数控系统有一定的参考价值。In order to meet the need of programming of four-axis machine with single table numerical control system for space cutter compensation, a method of programming of space cutter compensation vector model was presented, the post processing algorithm of space cutter compensation was improved. The method was successfully applied to the self-developed numerical control processing of four-axis machine of stair handrail elbow. The method relies on existing CAM software, and it has certain universal and certain reference value of the development of the four-axis numerical control system with the function of space cutter compensation.
