摘要

To find the optimal powder-mixed electrical discharge machining (PMEDM) option, this research defines a multi-criterion decision-making (MCDM) process. The 90CrSi steel workpieces in this project have a cylindrical shape. Additionally, five input variables—powder concentration, pulse duration, pulse off time, pulse current, and servo voltage—were picked for the examination. Additionally, the experimental design used the Taguchi approach. Additionally, the MCDM problem was addressed using the MAIRCA (Multi-Attributive Ideal-Real Comparative Analysis) technique in order to achieve both a low electrode wear rate (EWR) and a high material removal speed (MRS). The MEREC (Method based on the Removal Effects of Criteria) technique was also used to determine creation weights. Lastly, the most suitable option for PMEDM cylindrically shaped pieces is provided.
