Abstract:

In this study, the effects of the cutting parameters (cutting speed, feedrate, depth of cut) and coating layer onto the flank wear and surface quality ofthe product have been investigated.Of the cold work steels that are used in the automotive industry, especiallyin die making industry, DIN 1.2738 (AISI P20) has been machined with variouscutting parameters using two diiferent cutting tools, each having the samemicrostructure but different coating layers. After these operations, the effects ofthe coating layers were evaluated. The coating layer is T(C,N)+ Al2O3 + TiN forISCAR IC 9007 and TiAlN for ISCAR IC 907, and are of the ISO CNMG 120408type inserts that are recommended for semi-rough operations.As the results of the experiments, it was observed that TiNAl coatedinserts have positive effects on the flank wear and surface quality, compared tothe T(C,N)+ Al2O3 + TiN coated inserts.
