探讨了电火花加工过程中电参数设置与工件表面质量的关系。电火花加工过程中电参数的选择不仅影响加工效率,也会影响加工质量。首先分析了影响工件表面粗糙度的因素,然后在35P电火花机床上对一些主要因素进行了实验研究,找到了这些因素对表面粗糙度的影响规律。研究结果为改进生产工艺、提高表面质量提供了参考。 The relationship between electric parameter setting and workpiece surface quality during EDM is discussed. The selection of electrical parameters during EDM not only affects the processing efficiency, but also affects the processing quality. Firstly, the factors affecting the surface roughness of the workpiece were analyzed. Then, some main factors were studied experimentally on the 35P EDM, and the influence of these factors on the surface roughness was found out. The results provide a reference for improving the production technology and improving the surface quality.
