Ni-Ti 형상기억합금의 전해가공을 이용한 미세 그루브 가공 특성연구 = A study on the characteristics of micro groove process using electrochemical machining for Ni-Ti shape memory alloy

다국어 초록 (Multilingual Abstract)

Electrochemical micro machining, the anodic dissolution process is considered to effective advantaged micro machining method which possess several advantages on electrically conducting and difficult to machine materials. Ni-Ti SMA(Shape Memory Alloy) is composed of approximately 56% Nikel and 44% Titanium by weight. This material is able to function as to transform specific shape from a certain deformation when the alloy is heated. However, Ni-Ti SMA is easily to loss characteristic that shape memory as a traditional machining process by reason of generating heat at contacting area between material and tool. Therefore Ni-Ti SMA is suitable electrochemical machining that needless contact a tool to material.
In this paper, characteristics of micro groove process are studied on electrochemical machining to change tool diameter and distance between material and tool electrode.
