Abstract: In order to optimize the processing of the highspeed dry hobbing machining, the thermalforce coupling and the influences of processing parameters were analyzed. At first, theoretical modeling of cutting force and cutting temperature of dry hobbing machining was established based on the technical features of highspeed dry hobbing. On the basis, FEM simulation analysis of cutting temperature of each hobbing cutter teeth was proposed to obtain the temperature distribution of the rake face of hobbing cutter. It lays the basis of simulation study of hobbing machining. Then, the influences of feed rate and speed of hobbing cutter on hobbing machining was analyzed with the goal of highest cutting temperature. Finally, experiments of highspeed dry hobbing machining were proposed. The results show that the cutting temperature rises rapidly and then tends to reduce and stabilize slowly as the rise of the rotation speed of hobbing cutter. The high speed can save energy consumption. The research provides the guidance for the optimizing strategy of the processing of highspeed dry hobbing machining, and it lays the a theoretical basis for the design and manufacture of the hobbing machine.
