Experimental Investigation on Cutting Tool Performance of Newly Synthesized P/M Alloy Steel Under Turning Operation

Abstract

Components processed through powder metallurgy (P/M) route replace the parts in many of the industrial sectors. The present work focuses on cutting tool characteristics of a newly synthesized Fe–1%C–1%W–1%Ti P/M alloy steel for turning of AISI 1020 steel. In this work, the cutting tool behaviour of P/M tool is also compared with conventional high-speed steel tool. $$\hbox {L}_{{9}}$$ orthogonal array design matrix is employed in conducting experiments in an all-geared headstock lathe. The selected cutting speed, feed rate and depth of cut are used as the influencing parameters in turning AISI 1020, and the cutting tool behaviours of P/M alloy steel tool are evaluated concerning surface finish and tool flank wear. The outcome of the present work reveals that the tool processed through P/M route has exhibited better performance compared to the HSS cutting tool. ANOVA and signal-to-noise ratio were employed to study the effects and contributions of working parameters on the surface finish and cutting tool flank wear of the component. The performance analyses have shown that the cutting speed and feed rate are the most dominant factors for the tool wear and surface finish, respectively. The confirmation test has ensured the validity of the regression model developed in the present work.
