【 摘 要 】

Bulk metallic glass (BMG) is one of the predominant materials that are progressively used in the aerospace, medical devices, electronics, sporting goods, and engineering materials. Making of components by BMG is still confrontation. Conventional methods of machining are restricted in use due to more tool wear and slower processing efficiency. Non-traditional methods of machining have been widely used for processing hard materials. Wire electrical discharge machining (WEDM) is one among the promising approaches of machining for hard and conductive materials, especially for the new BMG metal material. The preliminary aim of this exploration is to predict the temperature field distribution using the modified Gaussian heat source mode during WEDM multi-pulse discharge process. The effects of various variables (pulse off time and peak current) on the pit depth and surface roughness were investigated. The influence of the main parameters on the machining performance was investigated using Taguchi's orthogonal arrays. The excellent surface quality is obtained at the optimized condition of a pulse on time of 4 & mu;s, pulse off time of 25 & mu;s, and a peak current of pulse on time.
