ABSTRACT:
A rail system for positioning a toolhead above a workpiece uses a rack cut into one edge of the rail and driven by a pinion gear whose shaft is approximately perpendicular to a workpiece to couple the rail to the toolhead. Multiple rollers placed on the toolhead allow contact between the toolhead and the rail to be effectively continuous despite the cutting away of as much as or more than two-thirds of the rail edge to provide rack teeth. Separating thickness axis containment from transverse with a square rail edge and separate thickness axis and transverse rollers allows the toolhead to follow a rail as the rail flexes over a curved surface with minimal position error. Several variations in rail, bearing, and rack implementation can realize comparable results.
