摘要

电火花加工脉冲放电的统计学研究表明电参数与加工质量间存在一定的规律性。为实现电火花加工小孔圆柱度误差的合理控制，通过大量的工艺试验研究放电参数与小孔圆柱度间的规律是十分必要的。提出了多截面直角坐标测量方法，实现了小孔圆柱度的定量评定。在此基础上，采用正交试验研究了放电参数（开路电压、电流，脉宽，脉间，抬刀周期）对小孔圆柱度的影响。结果表明：脉宽对圆柱度的影响最为显著，开路电压次之，其余三个参数的影响较弱；同时也得到了以圆柱度误差最小为评价目标的一组放电参数。

Abstract

The statistical study shows that there are some relations between the electrical parameters and the machining quality in electrical discharge machining (EDM). In order to control the cylindricity error of small hole machined by EDM

it is very necessary to study the relations between the electrical parameters and the cylindricity of small hole by technology experiments. In the course of studying

a measurement of multiple sections by cartesian coordinate is proposed

and then the cylindricity quantitative evaluation of hole is achieved. Based on the method above

an orthogonal experiment is used

and the effect of some main electrical parameters (voltage

current

pulse width

inter pulse and tool-lifting) on cylindricity of small hole is studied. The results indicate that pulse width affects cylindricity most distinctly

the voltage is secondary

and the effect of rest parameters is weak. The discharge parameters combination is achieved to purchase the least cylindricity error.
