Relationship between Machining Characteristics & Current Efficiency in Electro Chemical Machining of Ni-Ti Shape Memory Alloy

Ni-Ti 형상기억합금의 전해가공에서 전류효율과 가공특성의 관계

This study was performed to investigate the electro-chemical-machining (ECM) characteristic of Ni-Ti Shape Memory Alloy (SMA). From the experimental results, we could gain optimal electro-chemical conditions to bound with lesser machining effect and better surface roughness than any other machining methods to workpiece at the same time. At these conditions, current efficiency was, for especially ECM working of Ni-Ti SMA, approximately 100% and high frequency pulse current was detected.
