Abstract: : Incurrent times wire arc additive manufacturing is becoming popular and alternate to conventional machining because of its eco-friendly as wastages. Wire arc additive manufacturing (WAAM) develops the parts by depositing wire material one layer above other because it is based on old technology i.e., welding. It even has ability to generate complex parts. As WAAM requires post processing to obtain the better surface and accuracy of dimensions. To study about the post processing of WAAM specimen, in this work Wire cut EDM is used, which can machine complicated shapes with high accuracy for any conducting material without taking into account the hardness of the material. Selection of input parameters is the key for better surface finish in Wire EDM. Mechanical properties are used for testing of specimen are Tensile test, Compression test, and Izod test. In this study Pulse on time, Wire tension, Servo Voltage with three levels were considered as input parameter and Material removal, Surface roughness are considered as output responses. Response surface Methodology is used for designing the experiment. It is observed that wire tension plays vital role in surface finish, pulse on time is important in material removal but not in surface finish. Servo voltage predominant for surface roughness.
