Gear Grinding Usually, gear grinding is performed after a gear has been cut and heat-treated to a high hardness Grinding is necessary for parts above 350 HB (38 HRC), where cutting becomes very difficult. Teeth made by grinding are usually those of fine pitch, where the amount of metal removed is very small. In addition, grinding of gears ...

Unfortunately, gear grinding is an expensive and time consuming process, so that high grinding parameters are preferred to increase productivity of this manufactu- ring operation. Nevertheless, such parameters may cause serious damage to the surface layer of gear teeth, which was clearly shown in [2][3].
