Abstract
In cutting process, cutting condition has a strong effect on tool life and machining speed. It is required that high production system which balances tool life and production efficiency in factories. In this study, we focused on heat energy generated by cutting as the cause of tool wear. In order to equalize a cutting energy, cutting tests which at a certain material removal rate and wear mode of tool was estimated. In addition, two dimensional cutting was performed to calculate cutting energies. Furthermore, cutting temperature in each condition was measured by tool-work thermocouple measurement. At the these results, we clarified the correlation between the tool wear and cutting temperature and consider the effective search method for an optimum cutting condition.
