摘　　要：通过正交实验与对比试验,对恒电压下圆柱管状电极电弧铣削加工的加工特性和加工规律进行分析研究。分析电流、进给速度、工件移动速度、气压等因素对电弧铣削加工效率和电极损耗两项指标的影响。通过对直观分析表和效应曲线图的分析得出在恒电压U=25 V条件下电弧铣削的最优加工组合为:I(80 A)f(-0.8单位/s)v(80单位/s)P(5 MPa),以及该条件下各因素对电弧铣削加工的影响规律与特性。The processing characteristics and the rules of cylindrical tubular electrode arc milling are analyzed and researched in a constantly voltage through the orthogonal experiment and contrast test. The impact of current,feed speed,work- piece speed,pressure and other factors on the two indexes of arc milling machining efficiency and electrode wear are analyzed. The optimal processing combination of arc milling is: I( 80A) f(- 0. 8 unit / s) V( 80 unit / s) P( 5 MPa),in the condition of constant voltage U = 25 V,obtained through the analysis of the table and the effect curve,as well as the impact rules and characteristics of various factors on arc milling under the conditions.
