Abstract
High-speed cutting, if feasible, may improve the efficiency of machining. Since the higher the cutting speed, the larger the temperature rises, the high-speed cutting should considerably promote the thermochemical wear and then drastically reduce the life of tool. In this study, we focused on extremely short time cutting. In this method, tool temperature can be considerably suppressed by controlling the thermal diffusion time between a cutting tool and work piece, i.e., thermochemical wear can be suppressed by far less level. Through experiments, the effects of the cutting period during a single pass on the tool temperature and tool wear were investigated.
