摘　　要：高硅铝电火花加工受到多个工艺参数的影响,而且各个工艺参数之间还存在着相互制约的关系。本文通过对高硅铝合金电火花加工,重点分析了间隙电压、峰值电流、脉冲宽度和加工时间对工件加工速度的影响,并对实验数据采用正交试验的方法进行处理并综合分析,得到3组最优组:直接分析最优组、极差分析最优组、曲线分析最优组,通过验证得到更优参数组。研究结果为实现高硅铝合金高效高精度的电火花加工提供了参考。The technological effect of high Si- Al alloy EDM is affected by multiple processing parameters,and there is the interdependent relationship between the various processing parameters. In this paper,though processing High Si- Al alloy by EDM,the influence of gap voltage,peak current,pulse width,processing time on the workpiece speed is analyzed,and the experimental data are processed and analyzed by orthogonal test.,getting 3 optimal groups,which are the optimal group by direct analysis,the optimal group by range analysis,the optimal group by curve analysis,through the verification,finding the best parameter. The results provide a reference for the High Si- Al alloy EDM which is high efficiency and high- precision.
