摘　　要：为探究电火花辅助铣削在不同性能材料加工中的差异性,采用属性差异大的钛和铜两种材料进行加工,并对比分析了电火花辅助铣削加工和传统铣削加工后的表面质量。由于电火花热辅助的作用,两种材料在EDAM加工后的表面粗糙度减小及黏屑的附着程度均有降低。不同属性的材料在电火花辅助铣削加工后的表面质量呈现了明显的差异,当材料具有较好的导热性与易加工属性时,一定程度上能更好地抑制切削后表面黏屑的形成。此外,在不同放电能量下的电火花辅助铣削加工中,两种材料加工后的表面粗糙度均有随着电容值的增大而减小的趋势。In order to explore the differences of EDM-assisted milling in the processing of materials with different properties,this paper uses titanium and copper materials with different properties for processing,and compares and analyzes the surface quality after EDM-assisted milling and traditional milling.It is found that the surface roughness and the adhesion of debris of the two materials decreased after EDAM processing due to the thermal assistance of electric spark.The surface quality of materials with different properties is obviously different after EDM-assisted milling.When the materials have good thermal conductivity and machinability,the formation of surface chips after cutting can be better inhibited to some extent.In addition,in EDM-assisted milling with different discharge energy,the surface roughness of the two materials after machining tends to decrease with the increase of capacitance.
