【 摘 要 】

Generally, Ni based superalloys are used as combustor material owing to its high temperature resisting properties. These materials are also having high strength and hence, they are difficult-to-machine. Producing components of these materials with complex shapes employing traditional machining techniques is practically near to impossible. This problem can be addressed by using WEDM technique. The current research aims to study the effect of wire related parameters and servo feed on material removal rate (MRR) and wire wear rate (WWR) during WEDM of waspalloy. Experimentation has been conducted as per one-factor-at-a-time (OFAT) approach and optimum solution is obtained by graphical analysis. It is observed that wire feed rate of 4 m/min, wire tension of 11 machine unit, and servo feed of 2050 mm/min provide highest value of material removal rate.
