Parameter optimization in the enhancement of MRR of titanium alloy using newer mixing method in PMEDM process

Abstract The addition of powders in electrical discharge machining (EDM) reduces the breakdown strength liquid dielectric, thereby enhancing occurrence early spark, and aids machinability. Challenges occur sustainability powder mixed (PMEDM) process terms homogeneity powder-dielectric mixture adverse effects these on impellor pump, maintaining concentration powder–dielectric for a wide range at varied size. In this investigation, an attempt is made to address challenges limitations performing PMEDM by developing newer mixing method PMEDM. Taguchi L18 orthogonal array has been selected study material removal rate (MRR) titanium grade 5 alloy. Gap current, duty factor, pressure dielectric fluid, type powder, have considered as variables. results found be satisfying with increase MRR. confirmation experiments indicate considerable This system capable sustainable manufacturing irrespective nature particle size additive powders, that are permissible inter-electrode gap it restricts added process.
