Abstract

In this study, the machining parameters of electrical discharge machining (EDM) are varied to study the effects of electrical discharge energy on material removal rate and surface roughness of NdFeB magnet. Moreover, the micro-cracks on the machined surface induced by EDM are also examined. The experimental results reveal that the MRR increases with the electrical discharge energy. The surface cracks on the machined surface are more serious when the discharge energy is higher. Thus, using EDM process to machine sintered NdFeB magnet depends on setting the machining parameters to prevent surface crack.
