Optimization of Turning Process Parameters for AISI (M3) Material: As a Case of Multi response Optimization

Abstract

The present study focuses on the multi-objective optimization of turning process parameters for the AISI M3 tool steel material. The turning process is performed using a CNC machine. The experimental conditions are characterized by a lack of moisture in the surrounding environment. The primary objective of this study is to identify the optimal turning process parameters that will provide both the highest surface polish and the highest material removal rate concurrently. The study determined that a cutting speed of 300m/min, a feed rate of 0.15mm/rev, a depth of cut of 0.75mm, and a nose radius of 1.2mm resulted in the optimal values for both Ra and MRR in the turning process. The specified criterion for this step is nominal. Both the values of Ra and MRR exhibit an upward trend as the cutting speed increases. Both the values of Ra and MRR drop as the feed rate increases. The values of Ra and MRR first rise and subsequently decline. The values of Ra and MRR both rise as the nose radius increases.
