Abstract
This paper presents the simultaneous micro-ED/EC milling that provides significantly improved surface integrity and dimensional accuracy when compared with micro-ED or micro-EC milling alone. The concurrent occurrence of electrochemical reaction and electrical discharge is attained by exploiting partially deionized water with appropriate process control. Machining speed is judiciously adjusted to promote electrochemical reaction for improving surface finish. Concurrently, short voltage pulses localize dissolution zone for greater precision while also remove micron-thick layer generated by discharge craters from the machined surface. Micro-shapes with enhanced surface finish and dimensional accuracy are produced to demonstrate the feasibility and capability of the aforementioned approach.
