milled

Milled is the past tense and past participle of the verb mill. It describes material that has been ground, crushed, or reduced in size by a milling process. The term is used across food production, metalworking, woodworking, and construction to indicate that an item has undergone milling.

In food production, milling refers to grinding grains into flour, meal, or powder. Differences in method include stone milling, which uses stationary stones to grind, and roller milling, which uses rotating rollers to fracture and sift. The resulting products are often labeled as milled flour or milled grains.

In manufacturing and engineering, milling is a machining process that uses rotary cutters to remove material from a workpiece. A milled component typically has flat or contoured faces produced by milling operations, and the term applies to metals, plastics, composites, and wood. Examples include milled aluminum parts and milled wooden panels.

In usage, milled materials may be subjected to further processing, such as sifting, annealing, or coating. Milling is distinct from grinding, though both involve size reduction; milling emphasizes material removal with cutting actions. The word milled appears in technical specifications, recipes, and industrial descriptions to denote completion of the milling step.
