High-speed dry hobbing is a high efficiency green technology in gear manufacturing developed in recent years

which has overcome the disadvantage of traditional gear machining including low productive efficiency

high productive costs

polluting environment and being hurtful to worker health etc.Based on the principium of metal cutting

heat transfer and gear hobbing

the cutting temperature model of high-speed dry hobbing is built.By using finite element analysis（FEA）

the cutting temperature field of hobbing is analyzed.Through high-speed dry flying cutter cutting simulating the hobbing experiment and combing theoretical simulation and experiment result

the varying relation of cutting temperature and cutting parameter in high-speed dry hobbing is synthetically analyzed.
