Abstract:
A work drive orienting system for a machine tool, such as a multiple belt grinder, comprises a head stock and a tail stock for supporting the workpiece to be machined, a locator retained by a spider in the head stock chuck, and a proximity sensor located in the loader operatively associated with the machine tool. The workpiece has journals at opposite ends, and spaced eccentric portions, such as cam lobes; also, a locating pin projects axially from one end of the workpiece. The locating pin has a predetermined angular relationship to the spaced eccentric portions of the workpiece. The locating pin must pass alongside the locator, which has a cylindrical body with a projecting tab, before power is supplied to the head stock and/or tail stock to drive same. A proximity sensor, located in the loader, scans an approximately 70. degree. arc on the workpiece, for the presence of eccentric surfaces, such as cam lobes.
