The dry hobbing is a gear manufacturing method capable of reducing environmental pollutions and product costs. However, it causes high cutting temperature and shortening tool life. In order to solve these problems, we have proposed the new gear hobbing method - the vibration hobbing. The vibration hobbing gives axial micro vibration to the hob by external vibration generator during gear processing. Our study showed that the vibration hobbing method was effective for reducing the cutting heat under the dry environment.
The purpose of this study is to establish a model to understand the features of our vibration hob system, and decide the suitable cutting condition for the vibration hobbing. This paper explains the structure of our vibration hobbing machine. Next, we propose the model of vibration hob system, and show the frequency response curve calculated from our model is good agreement with our experimental result. Finally, we consider the suitable processing conditions experimentally.
