Abstract

Hard turning has found to be a viable method for machining hard parts like cemented tungsten carbides. This method is effective and efficient with polycrystalline diamond (PCD)—a superhard cutting tool with a longer tool life. The objective of this paper is to optimize the cutting parameters for multimodal grade of PCD. Round full face PCD insert with hardness of greater than 9000 HV is used for turning WC–Co–Ni–Cr (15% Binder) mill rolls on CNC lathe. The responses like taper, cycle time, flank wear, and maximum spindle load are recorded. Optimal cutting parameters have been obtained from consideration of different responses. Abrasion on the flank is found to be the major wear mechanism.
