Abstract
In the current study, various machining variables are investigated in relation to the abrasive mix electrical discharge machining (AMEDM) performance of aluminium LM25/SiC MMC. An originality of this experiment lies in the fact that silicon carbide abrasive mix EDM has been successfully applied to aluminium LM25 grade metal with 5% SiC reinforcement. The research was conducted with aluminium LM25/SiC MMCs with abrasive mixed dielectric fluid using Box-Behnken design (BBD) of response surface methodologies (RSM). The ANOVA has been performed to identify machining parameters that significantly influenced machining performance. The purpose of this article is to provide directions for optimizing the AMEDM parameters, such as voltage, pulse rate, and powder concentration, based on the material removal rate, wear rate, and roughness of the surface. It is found that discharge current contributes significantly to the improvement of material removal rate (99.23%), surface finish (98.01%) as well as the tool wear rate (40.56%), respectively. Which enhanced the performance characteristics of abrasive mix EDM.
