tively, using different gears are shown in Figs. 6 and 7. Note how each correlation gives symmetrical curves for all gears. Peripheral speed Peripheral speed is determined by wheel diameter and ro-tational speed. The correlation between wheel diameter and rotational speed is: All grinding wheels have a resistance threshold. If a grinding

To establish the precise grinding material removal rate, the different kinematics of processes such as traverse grinding [7 ,8 11–13], reciprocal grinding, plunge grind-ing, and plunge grinding with oscillations have to be con-sidered. In this way, the active grains load on the GWAS in each variant of the internal cylindrical grinding process

Cylindrical grinding can also be curved or steep, and can be performed to produce different shapes [2]. Moreover, the internal grinding has the same phenomenon as cylindrical grinding, except that it is for internal rotary parts. The internal grinding is a high-speed operation, because the grinding wheel rotates at a speed of 30,000 rpm or even ...
