Abstract
Recently, the Electrochemical Discharge Machining (ECDM) process has become increasingly important in the machining of materials that are electrically conductive and non-conductive, brittle and of high hardness. This research aims to examine how well ECDM performs while drilling tiny holes in HSS milling cutters. Based on a survey of the literature, the three main affecting factors voltage, electrolyte concentration and duty cycle have been chosen. Utilizing Design Expert System 13, the Box-Behnken method of surface approach was used to create the experiment design.The experiments have been conducted by the combination of Sodium Hydroxide (NaOH) and Sodium Nitrate (NaNO3) each 50% by weight basis and measured outcomes are: (i) Metal removal rate (MRR) (ii) Tool wear rate (TWR). The selected objective functions of maximization of MRR and minimization of TWR. The created multi objective optimization models feature highly interdependent chosen parameters. The confirmatory trials demonstrated that there is a less than 5% difference in results between the experimental and theoretical model values.
