Thrufeed centerless OD grinding: Parameter relationships ...

The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality. The regulating wheel acts like a brake, controlling the rotational speed and thrufeed rate of the workpeice. An angular-topped workrest blade supports the workpiece as it passes through the grinder between the grinding and regulating wheels.

Grinding wheel wear - Wikipedia

The longevity and cutting ability of a grinding wheel can be affected by the grinding forces generated while in use. Experimental investigation has revealed a direct relationship between cutting speed, wheel geometry, chip geometry, and the grinding forces namely the resultant normal force component (F n), the tangential force component (F t), and their ratio when in contact with a workpiece.
