Analysis of Thermal Displacement of PCBN Tool Holder for Machining Accuracy in Hard Turning
하드터닝에서 CBN 공구홀더의 열변형이 가공정밀도에 미치는 영향
Abstract
The hard turning is a turning operation performed in high strength alloy steels (HRC>30) in order to reach surface roughness close to those obtained in grinding. This is possible because of availability of improved tool materials (polycrystalline cubic boron nitride. PCBN), ad more rigid machine tools. According to many previous work of hard turning mechanism, the maximum temperature of cutting can be raised up to 100
