摘要/Abstract

摘要： 为了实现电解加工深小孔的精度控制，建立线性去除率动态数学模型，分析影响动态方程的工艺参数，通过在镍基合金上进行电解加工深小孔试验，分析了脉冲宽度、工具电极进给速度、工具电极绝缘层有无裸露对深小孔加工精度的影响。结果表明：采用较大的脉冲宽度、较大的工具电极进给速度、绝缘层覆盖全部工具电极，有利于提高孔的加工精度。

Abstract: In order to realize the processing accuracy of the deep hole on hard-cutting alloys in the pulse electrochemical machining, a dynamic math model for the linear removal rate is established and the effect of process parameters is analyzed also. The effects of pulse width, tool feed speed and insulating layer on the tool are studied experimentally. The experiment results show that the longer pulse width, higher feed speed and insulation of all outside surface of tool can improve the processing accuracy of the deep hole.

Key words: machinofature technique and equipment, pulse electrochemical machining, deep and small hole, linear material removal rate, machining accuracy
