The rack and pinion mechanism is used in rack railways, where the pinion mounted on a locomotive or a railroad car engages a rack usually placed between the rails, and helps to move the train up a steep gradient. It is also used in arbor presses and drill presses, where the pinion is connected to a lever and displaces a vertical rack (the ram).
Arbor presses can be mounted on a work bench, wall, or pedestal. The base is usually constructed of cast metal. A ram provides the force; it may be square or round. The ram is usually driven by a rack and pinion. Higher force arbor presses have a further gear reduction. [1] Forces are usually generated by manual or hydraulic input. [2]

The name shaper relates to the fact that the cutter engages the part on the forward stroke and pulls away from the part on the return stroke, just like the clapper box on a planer shaper.
