| 摘 要： | 数控机床的加工是通过数控指令来实现的,理想的数控指令可得到理想的刀具轨迹,但在实际加工中,由于运动误差,实际轨迹与理想轨迹有差异,致使这些指令不能得到理想的轨迹.作者结合数控机床各部件间的运动形式,对数控指令修正方法进行了研究,通过对数控指令加以修正,使加工轨迹控制在理想轨迹附近,改善了加工的质量,并以三轴数控机床为对象进行了实验验证,结果证明该修正方法有效的提高了机床加工精度.

| Abstract: | NC machining achieves the ideal of NC commands by NC control command to available to the ideal,but in actual processing,due to motion error,there are differences between the actual trajectory and the ideal trajectory,these instructions can not be the ideal trajectory,by the movement between the various components of the NC machine,the Method of the Correcting NC Command have been studied in the paper,so that processing of trajectory control in the vicinity of the ideal trajectory,improving the processing quality.And to three-axis CNC machine tools as experimental object,and test results verify that the correction method effectively improves machining accuracy. |
