slotting[′släd·iŋ] (mechanical engineering) Cutting a mortise or a similar narrow aperture in a material using a machine with a vertically reciprocating tool. Slotting (also grooving), a method of working metals and wood by cutting on slotting machines. It is used to produce mortises, keyways, shaped apertures, bevels, and notches. During the slotting process the slotting tool or ram usually performs reciprocating motion in the vertical plane, and the workpiece is fed to it. In metalworking, slotting is a low-output process with low machining accuracy; it is often replaced by milling or broaching. |
