Grinding Operation an overview ScienceDirect Topics

The peripheral cut-off grinding process is subdivided into oscillation grinding with a stationary workpiece and rotational cut-off grinding where the workpiece is moving around its longitudinal axis. The main advantage of rotational cut-off in comparison to other techniques is the small contact length.

Grinding Machine operation working principle

2020-8-5  Grinding is a metal cutting process in which the material is removed from the workpiece by the abrasive action of rotating cutting tool known as a grinding wheel which rotates at a high speed (v= 10-80 m/s) while the work is fed past the wheel at a rate of 0.2 m/s to 0.6 m/s. It has some similarity with up milling operation except that the cutting points are irregularly shaped and randomly distributed.
