Abstract

Objectives: The scope of this experimental work of electrical discharge machining (EDM) process with and without the addition of abrasive powder while executed on M2 tool steel for the advancement in surrounding safety factors to meliorate the surface quality. Methods/Statistical Analysis: Taguchi’s L36 mixed orthogonal array is used after identification of most appropriate six input parameters (polarity, electrode type, concentration of abrasive, discharge current, and gap voltage and duty cycle) for maximum MRR and minimum TWR, and SR. Findings: To recognize the significant factors ANOVA is used and TOPSIS determine the 10.47% overall improvement in all responses with the optimal level of process parameters after confirmatory test. Energy dispersive X-ray (EDS) and Scanning electron microscope (SEM) analysis applied to examine the surface quality. Application/Improvements: This study finds the downfall of titanium from powder metallurgy tool electrode (CuTi) and deposition of aluminium material from PMEDM may also be implemented to improve the method of computation and precision.

Abstract

Objectives: To solve the multi-response trouble with the influence of process parametric quantities of the electric discharge machining (EDM) on M2 tool steel with unlike electrodes for maximum material removal rate (MRR) and minimum tool wear rate (TWR), surface roughness (SR). Methods/Statistical Analysis: Taguchi mixed DOE was used to determine the optimal setting for prime response and further transformed it into signal-to-noise (S/N) ratio and weighted with the most prominent S/N ratio of optimal level for each factor. It was found after conformation examination that the best results of responses were with powder metallurgy copper-titanium tool at straight polarity in average addition of aluminium powder during PMEDM at minimum current, duty cycle values and maximum value of gap voltage. The weight loss method is used for the study. Findings: The restraint and effectuality of this approach shall make it hypnotic to practicians for licking the multi-response trouble in a broad range of this technique. Application/Improvements: It may further enforced to improve the veracity and effective to use in any field of engineering applications with petty computation.
