Özet

In this study, effects of cemented carbide coated with TiC+TiN, coated with TiC, uncoated and CBN on the machinability of AISI 410 martensitic stainless steel was investigated. In the experiments chip root morphology, cutting forces and surface roughness were determined. Experiments were done in the dry turning conditions. The cutting speed, feed rate and depth of cut were kept constant as, 60 m/min, 0.12 mm/rev and 1.2 mm respectively. Cemented carbide tool coated with TiC+TiN gave maximum cutting forces. Although CBN gave the minimum cutting forces, it was observed that it fractured in a shorter machining length. The optimum values of cutting force and surface roughness were obtained from cemented carbide coated with TiC.
