Abstract

TiNiCo Shape memory alloy are most usable material in the field of biomedical, aerospace and robotics applications due to their unique class of properties. Super elasticity, shape memory effect and two phase transformation behaviour of these alloys make unique material. Machining of shape memory alloy is quite difficult through traditional machining process hence non-traditional machining of these materials is suitable. Ti50Ni40Co10 shape memory alloy was developed through Vacuum arc melting furnace for the present study. Wire electro discharge machining (A Non-traditional Machining) was used for machining of selected alloy. Moreover TOPSIS method implemented for the parametric optimization of WEDM. Pulse on time, wire speed, Servo voltage, Pulse off time and servo feed were considered as process parameters and productivity rate and surface quality (average roughness) were consider as output process parameters of WEDM. To see the effect of machining on the machined component EDX analysis has been carried out of optimal process parameters setting. 4.72 mm3/min productivity rate and 1.26 μm average roughness was found at optimal combination of process parameters of WEDM. Moreover, during the EDX analysis Cu, Zn, O and C were noticed on the machined surface including the parent material.
