Wire Electrochemical Machining (WECM) combines the advantages of electrochemical machining working principle with the kinematic of wire EDM which is properly applied for fabrication of micro-features. WECM utilizes the advantages of these processes to enhance machining quality. Exceptional features of shape memory alloys (SMA) make them encouraging for widely advanced industrial applications. These difficult-to-cut materials micromachining without affecting original properties plays crucial role. Through this paper, an attempt has been made for the improvement of WECM during micromachining of nitinol SMA and explains the fundamentals of WECM process. This paper discusses various elements of developed WECM system. The paper also includes some experimental results of micro-slit machining by utilizing developed WECM setup and energy interaction behavior during fabrication of microslits of nitinol SMA. The homogeneous microslit with average slit width 111 µm with 1.68 µm standard deviation has been fabricated at 5V pulse voltage and 1.4 µm/s wire feed rate.
