Oct 04, 2019· Mastication Definition. Mastication is the mechanical grinding of food into smaller pieces by teeth; it is essentially a technical word for "chewing".Mastication breaks down food so that it can go through the esophagus to the stomach.Breaking down food into smaller pieces also increases its surface area so that digestive enzymes can continue to break it down more efficiently.

Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

(OD) grinding is a system in which grinding surfaces are rotated, and a rotating stock piece is introduced next to the abrasive wheel. This results in a circular shape and form, and the system comes in two versions: through-feed and in-feed. Through-feed OD grinding introduces a stock piece at one end of the abrasive materials, and it passes across
