Material Removal Rate - an overview | ScienceDirect Topics
Material removal rate (MRR) is the amount of material removed per time unit, directly aiming at the process productivity. In roughing operations and the production of large batches, this needs to be maximized. However, in finishing operations, it is a factor to be put on hold, bringing roughness and precision to the forefront.

Grinding (abrasive cutting) - Wikipedia
Creep-feed grinding (CFG) was a grinding process which was invented in Germany in the late 1950s by Edmund and Gerhard Lang. Normal grinding is used primarily to finish surfaces. But CFG is used for high rates of material removal, competing with milling and turning as a manufacturing process choice.
