Theoretical and Experimental Research on Cutting Temperature of High-speed Dry Hobbing

高速干式滚齿加工是近年来发展的一种高效率的绿色齿轮制造技术,它克服了传统齿轮加工生产效率低下、生产成本高、污染环境及危害工人身体健康等缺点。基于金属切削原理、传热学理论及滚齿加工原理,建立了高速干式滚齿的切削温度模型,应用有限元法仿真分析了滚刀的切削温度场;通过高速干式飞刀铣齿来模拟滚齿实验,结合理论仿真和实验测量结果,综合分析高速干式滚齿的切削温度与切削参数之间的变化规律。

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.
