Summary:The present work investigated some machinability study, regression modeling and optimization aspects during dry hard turning of AISI 52100 bearing steel (55 ± 1 HRC) using economical coated carbide insert which is little being investigated as per literature study. The multilayer coated carbide insert present itself an alternative avenue to costly cBN and ceramic insert in machining of difficult-to-cut bearing steel at hardened state. The steady progression of flank wear with no chipping and fracturing is observed during studied range. Abrasion is predominant wear failure seen in the experiment. Quadratic regression model shows the accurate of results and may be implemented in dry hard turning environment. The optimum results are recommended as: cutting speed (110 m/min)-feed (0.04 mm/rev)-depth of cut (0.2 mm) while turning hardened AISI 52100 steel through coated carbide insert. At this optimized parametric conditions, the flank wear and surface roughness values are obtained to be 0.06 mm and 0.81 microns which is well within the criteria limit. The potential benefits of low cost coated carbide insert under dry finish turning of hardened bearing steel has been noticed at moderate cutting speed.
