Grinding (abrasive cutting) - Wikipedia

Creep-feed grinding (CFG) was invented in Germany in the late 1950s by Edmund and Gerhard Lang. Unlike normal grinding, which is used primarily to finish surfaces, CFG is used for high rates of material removal, competing with milling and turning as a manufacturing process choice. Depths of cut of up to 6 mm (0.25...

Pocket Guide to Grinding Technique - Atlas Copco

POCKET GUIDE TO GRINDING. When the abrasive is applied to the workpiece, rotational speed decreases as the abrasive is held back by the torque caused by grinding action and feed force. A great deal of the energy is lost through heat. The more feed force the operator applies to the tool, the lower the rotational speed.
