Comparative evaluation of conventional and wiper ceramic tools on cutting forces, surface roughness, and tool wear in hard turning AISI D2 steel

Recently, wiper ceramic inserts have emerged as a significant class of cutting tools, which are increasingly being utilized. This study considers the influence of the wiper inserts when compared with conventional inserts on the machinability parameters (cutting forces, surface roughness, and tool wear) obtained in hard turning of AISI D2 hardened steel. A plan of experiments was established considering hard turning with predetermined cutting parameters. An analysis of variance (ANOVA) was performed to investigate the machinability parameters using conventional and wiper inserts. With wiper ceramics inserts, machined surfaces with Ra < 0.8 mu m were achievable. Consequently, surface qualities (dimensional accuracy) in a workpiece of mechanical precision, IT < 7, are possible.
