Flank Wear Evaluation Of Cryogenically Treated ISO K313 WC/Co Inserts In Dry CNC Turning Of 2507 Super-Duplex Stainless Steel

For several years, there has been a relentless effort to utilize Cryogenic Treatment process on various tool materials in order to improve their wear resistance. 2507 Super-Duplex Stainless Steel cause rapid tool wear due to high cutting temperatures generated during machining which makes it very difficult to cut material. In the present study, evaluation of Flank wear of Deep Cryogenically treated ISO K313 Tungsten Carbide inserts with Cobalt as a binder was done during dry CNC turning of 2507 Super-duplex Stainless Steel. L9 Orthogonal Array, S/N ratio and Analysis Of Variance (ANOVA) were used in investigating and analyzing data obtained from experimentation and also to find optimum cutting parameters (i.e. cutting speed, feed rate and depth of cut). Scanning Electron Microscopy was employed in order to study various types of wear mechanisms. The results proved that Cryogenically treated inserts showed lesser Tool Flank wear than untreated ones which was confirmed through SEM analysis.
