A thickness planer is a woodworking machine used to plane boards to a consistent thickness throughout their length, producing two parallel faces. The machine references its cut from the underside of the board, so producing a completely flat, planed board requires that the underside already be flat before planing, which is achieved by face jointing with a jointer or hand plane, or by face planing with a planer and a jointer sled.
