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.

Metal removal rates for plunge grinding operations: when the diameter of the workpiece is greater than 20 mm, then the following metal removal rates ( Q'w in mm 3 /mm.s) are recommended; roughing – 1–4, finishing – 0.08 − 0.33. When the workpiece is less than 20 mm, roughing – 0.6 − 2, finishing – 0.05 − 0.17. .

Difference Between Machining and Grinding
Grinding. Machining is one bulk material removal process (i.e. high MRR). Thus it is economical and suitable to give proper size and also for semi-finishing. Grinding has low material removal rate and is preferred only for finishing. Accuracy and tolerance achieved by conventional machining operations are not so good.

Cutting, grinding, and finishing - The Fabricator
Knowing what you're trying to accomplish is the first step in choosing the right abrasive product. Completing rough grinding after a deburring operation requires a different process and products than does blending or finishing, for example. A common pitfall in surface finishing is using the same wheel no matter the job.
