On Ti-alloy machining, it is problem that tool life is shortened by heat converging at cutting edge due to its low heat conductivity and production of saw-tooth chip. In this research, effect of oblique cutting is verified with comparing Ti-alloy with some materials and it is examined which material property is mainly associated with cutting temperature in oblique cutting. As a result of measuring chip temperature, it was found that the temperature rise with an inclination angle does not occur in Ti-alloy cutting although the total cutting energy increases with increasing in the inclination angle. Same tendencies were obtained in SUS430 and Brass cutting while, S45C cutting, large temperature rise took place. Consequently saw-tooth chip generation is strongly related to little temperature rise with the inclination angle.
