分析了平行直纹展成电解磨削整体叶轮叶片的过切误差,得到了过切误差计算公式,提出了用圆锥磨轮和组合式五轴联动数控方案来消除过切误差的方法。
The over-cutting error of the whole impeller blade was analyzed by parallel ruled development. The over-cutting error formula was obtained. The method of eliminating the over-cutting error by using the conical grinding wheel and the combined five-axis linkage NC program was proposed.
