Broaching is a machining principle in which a single-pass linear (push or pull) cutting motion is imparted to a multi-toothed cutting tool—the broach—whose successive teeth each remove a thin layer of material (tooth rise), producing the equivalent of many sequential shaping passes in one stroke. This distributes the total cutting force per stroke across many teeth so that force per tooth remains manageable while total material removal and productivity are maximized, and it belongs to manufacturing processes / machine tool engineering, specifically the sub-domain of form-tool-based, single-motion cutting processes distinct from shaping, planing, and milling.
