Grinding (abrasive cutting) - Wikipedia

Selecting which of the following grinding operations to be used is determined by the size, shape, features and the desired production rate. 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
