Theoretical Corroboration of the Selection Criteria of the Breaking-in and Shape-Copy Gear Teeth Grinding Methods

Peripheral grinding and disk grinding are commonly applied (without any theoretical justification) for the purpose of flat circular grinding and sharpening of cutting tools, respectively. In this work, the effectiveness of a profile face grinding method of gear teeth using modular grinding-wheels over the breaking-in grinding method was theoretically validated. Moreover, it was found that the cutting zone temperature during face grinding is much lower than compared to that of peripheral grinding, which was attributed to a larger grinding wheel to work piece contact length. Analysis performed in this work showed that the grinding zone temperature appears to be affected by power consumption and a grinding depth, indicating the possibility of lowering the grinding zone temperature by reducing these parameters.
