초록

The purpose of this study is to investigate cutting characteristics and wear behavior in SCM440 steel with different cutting tools, CBN(Cubic Boron Nitride) and coated CBN. During the test coated CBN toolespecially with TiAlN showed better wear resistance behavior than orginal CBN tools. In the interruptedcutting condition, axial groove affected tool surface with impact force during the turning operation. Foradvantageous turning parameter in the interrupted process it is recommendable that lower speed. Also surface roughness showed better behavior in the coated CBN tool conditions than normal CBN conditions. Mainly this is caused by reduced friction between material and tool surface with coated layer.
