Evaluation of machining characteristics according to cutting condition of hardened steel in high speed machining

고경도 금형강(SKD61)의 고속가공에서 절삭조건 변화에 따른 가공성 평가

Recently high speed machining is being studied actively to reduce machining time and to improve machining precision. To perform efficient high speed machining, evaluation of high speed machinability must be studied preferentially and it can be identified by investigation of cutting force, tool wear and surface roughness. In this study. the cutting force and tool wear and surface roughness are investigated in case of various cutting conditions for hardened die steel.
