【Abstract】 The cutting temperature play an important role in the high speed cutting process,concerning about the tool wear, workpiece surface integrity and machining precision. Varying characteristics of cutting temperature in the high speed cutting process differ significantly from the ordinary cutting process with the different work materials,different cutting parameters and different cutting tools. A series of experiments are conducted by the aid of infrared ray temperature measuring system and the dynamic characteristics of cutting temperature in high speed milling aluminum alloy are revealed. The critical velocity value of high speed cutting aluminum alloy and a series of valuable conclusions about the varying characteristics of cutting temperature are put forward for the first time domestically, which are essential to the development of high speed cutting data base and to the optimization of high speed cutting process.更多还原
