Abstract: Temperature field measurements in the chip are performed during high speed machining of a low carbon steel (XC18) and a medium carbon steel (42CrMo4). An original mechanical device based on the propelling of a projectile by decompression of air allows to investigate a wide range of cutting speeds from 10 to 120 m/s. The technique of temperature measurement using the principle of pyrometry in the visible spectral range is realised with an intensified CCD camera with a very short exposure time. Temperature maps presented for the two steels confirm that the heating in the chip is not uniform and the presence of a maximal temperature area. The effects of cutting parameters such as chip thickness and cutting velocity are presented.
