反向差值对孔系加工精度的影响及其消除措施

Effect of Reverse Deviation on Machining Precision and Measure of Eliminating

分析了数控机床坐标轴定位轴线的反向差值对孔系加工精度的影响，并提出了消除反向差值对加工精度影响的方法。

The effect of reverse deviation of position axis of coordinate axises for NC machine on machining precision of system of holes is analysed.And the method of eliminating the effect of reverse deviation on machining precision is presented.The practice has proved that it is feasible.
