Abstract

Powder Mixed Electro-Discharge Machining (PMEDM) is being widely used in modern metal working industry for producing complex cavities in dies and moulds. It has been experimentally demonstrated that the presence of suspended particles in dielectric fluid significantly increases the machining efficiency of EDM process.In this paper, five parameters viz., concentration of silicon carbide (SiC) in dielectric fluid (P_c), peak current (I_p), gap voltage (V_g), pulse on C p g time (T_on) and duty cycle (η) were considered and varied to obtain optimal EDM performance characteristics including on Material Removal Rate (MMR) and surface roughness (R_a). Taguchi L8 orthogonal array was used for the design of the a experiment.The machining tests were conducted on AISI D3 tool steel work piece using copper electrodes and SiC mixed EDM dielectric-kerosene oil. Results of experiments show that concentration of SiCimproves MRR in PMEMD.
