Electrical discharge machining is an essential process in the domain of micromachining. However, many issues need to be solved to implement it in the industrial field. Increasing the machining rate still remains a challenging task in case of micro electrical discharge machining. It becomes impossible to machine a microfeature at a larger depth. Numerous investigators have investigated the positive effect of assistance such as magnetic field and ultrasonic vibration. This paper the discusses machining performance by simultaneously applying the ultrasonic vibration and magnetic field to the machining zone in micro-electrical discharge machining. The process performance is analyzed by measuring the performance characteristics such as material removal rate and taper of the microfeature. The results confirmed that the cumulative effect of each assistance ends in a better material removal rate and low taper of the microfeature.

电火花加工是微加工领域中必不可少的过程。但是，要在工业领域实施，还需要解决很多问题。在微放电加工的情况下，提高加工速度仍然是一项具有挑战性的任务。在更大的深度加工微观特征变得不可能。许多研究人员已经研究了磁场和超声波振动等辅助的积极作用。本文讨论了微放电加工中同时对加工区施加超声波振动和磁场的加工性能。通过测量微观特征的材料去除率和锥度等性能特征来分析工艺性能。
