Abstract

The present study addresses the machinability investigation in finish dry hard turning of high strength low alloy (HSLA) steel with coated ceramic inserts by considering cutting speed, feed and depth of cut as machining parameters. The technological parameters like surface roughness, flank wear, and economic analysis have been considered to investigate machinability performances. Twenty-seven set of trials according to full factorial design of experiments are conducted, and subsequently, analysis of variance, multiple regression method, Taguchi method, desirability function approach and finally Gilbert’s technique is employed for parametric influence study, mathematical modelling, multi-response optimisation, tool life estimation and economic analysis. Novelty aspects, the current work demonstrates the substitution of conventional, expensive and slow cylindrical grinding process, and proposes the most expensive CBN tool alternative using coated ceramic tools in hard turning process considering techno-economic and ecological aspects, which they are useful and efficient from the industrial point of views.
