Abstract
The major concern faced by various manufacturing Industry is to obtain the optimum machining variables maximum rate of material removed, low rate of tool wear and good value of surface integrity for a superalloys which is desirable characteristics from machining performance. The problem identified with the machining of the Incoloy alloy A286 which are considered very hard for getting machined which can be attained by Electrical Discharge Machining (EDM). The presented paper shows impact in various input parameters that is current, pulse on time and pulse off time and the output parameters that is material removal rate (MRR), electrode wear rate (EWR) and surface roughness (SR) based on the experiment performed that are thoroughly studied also during machining of Incoloy alloy A-286 workpiece while machining it with the copper as tool electrode material. Response Surface Methodology based Box Bekhen Design technique was used for Machining variables to get optimized. The parameters for optimization were later calculated.
