Abstract

Electro Chemical Machining (ECM) is a Non-traditional machining technique that has been used in the production of dies and it is originally as signed for manufacturing complex shaped components in defense and aerospace applications. The most important performance measures in ECM are material removal rate (MRR) and surface roughness (R_a). In this work, experiments were performed to determine parameters affecting material removal rate and surface roughness. The data obtained for performance measures have been analyzed using the design of experiments method. A considerably profound equation is obtained for the MRR and R_a using current, gap voltage, flow rate and gap setting parameters. SPSS software and C programming have been used to optimize the machining parameters of ECM.

Abstract

This paper deals with the development of mathematical models for electrical discharge machining process (EDM) and also an attempt has been made to optimize the machining parameters of EDM processes. Through hole drilling experiment has been conducted on mild steel and mathematical models are formulated for maximizing the metal removal rate and minimizing the surface roughness. SPSS and 'C' programming have been used to optimize the machining parameters for EDM.
