A mill is a device that breaks solid materials into smaller pieces bygrinding, 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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Powder processing often involves bulk powders, additives, or ingredients being milled for particle size reduction. A mill or grinder uses a mechanical action to break the material and reduce it to the required size. This may encompass a whole range of requirements from de-agglomeration and coarsegrindingthrough to finegrindingand classifying.

Machining - Wikipedia

Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removalprocess. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing.
