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.

Dry milling and fractionation of grain Wikipedia
Dry milling of grain is mainly utilized to manufacture feedstock into consumer and industrial based products. This process is widely associated with the development of new bio-based associated by-products. The milling process separates the grain into four distinct physical components: the germ, , fine grits, and coarse grits.

Mill (grinding) Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Cryogenic grinding Wikipedia
Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermo are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.

What Is Grinding and Its Working Principle and Type? Grinding
Sep 28, 2021During the grinding process, the grinding tool and the workpiece maintain a certain pressure and move relative to a certain trajectory to achieve micro-cutting, thereby obtaining high dimensional accuracy and low surface roughness. During dry grinding, generally no or only a small amount of lubricating abrasive is applied.
