ABSTRACT:
Method and apparatus for automatically dressing a regulating wheel to the required curvature for a centerless grinding operation. A dressing wheel is mounted for rotation about an axis which is inclined to a reference axis. The regulating wheel is mounted on a gimbal assembly which permits the axis of that wheel to be oriented as desired with respect to the axis of the dressing wheel, and the gimbal assembly is mounted on a carriage which is movable in directions parallel and normal to the reference axis. With the axis of the regulating wheel positioned as desired and the wheels in peripheral engagement, the wheels are rotated and moved relative to each other in a direction parallel to the reference axis to dress the regulating wheel. The angle between the axis of the dressing wheel and the reference axis is made to correspond to the angle at which the axis of the regulating wheel is inclined to feed workpieces past the grinding wheel in a centerless grinder. The gimbal assembly is adjusted to form the regulating wheel face with an angle for stock removal, and the carriage is positioned longitudinally to form the regulating wheel to accommodate workpieces a desired distance from the center line of the regulating and grinding wheels. In one embodiment, a follower affixed to the gimbal assembly engages a stationary template to pivot the gimbal assembly and form a desired stock removal contour on the face of the regulating wheel.
