Abstract
A method and apparatus for shaping the radial surface of a roller or other cylindrically shaped part in a single cycle. The preferred embodiment forms a crown geometry on one roller at a time using a CNC system to control a grinding surface in three axes. The grinding surface is controlled in two linear orthogonal directions (x and y) and around a circular axis (c) through corresponding stepper motors. In addition, the axial pressure applied by the grinding surface of the radial surface of the roller is controlled by an air pressure programmable regulator acting through a pneumatic cylinder. These four individually controlled, precise degrees of motion of the grinding surface, operating with a single rotating roller, permits extremely accurate crown shaping. The shaping is, in fact, so precisely controlled and so accurate that only one “cycle” of the grinding surface against the roller is required to achieve the desired crown profile.
