EDM with USM combination process of sintered NdFeB permanent magnet

摘要：

　　This paper presents an experimental investigation of the machining characteristics of sintered NdFeB permanent magnet using a combination process of electro-discharge machining (EDM) with ultrasonic machining (USM).Concentration of abrasive in the dielectric fluid is changed to explore its effect on the material removal rate (MRR).MRR of EDM /USM,conventional EDM are compared,machined surface characteristics are also compared between them.It is concluded that the combination EDM/USM process can increase the MRR and decrease the thickness of the recast layer.In the combination process,an appropriate abrasive concentration can improve its machining efficiency.
