Description:
Abstract:

A method for automatically sizing a ground surface utilizes a detector having a reference edge position provided adjacent the rotatable spindle of a jig grinder. The jig grinder spindle center is moved a distance from the detector's reference edge equal to the finished radius value of the surface to be ground, or any known distance to be used as a datum. A tool or grinding wheel mounted for relative movement to the jig grinder centerline along the U-axis is moved relative to the jig grinder centerline to clear the detector's pick-up edge. Then, with the grind side of the grinding wheel facing the detector pick-up edge, the wheel is lowered and outfed back along the U-axis while in a conventional dynamic grinding mode until the wheel's outermost cutting position is equal to or in proximity to the detector's reference edge position, which can be confirmed by laser, force or sound apparatus. When contact is made, the outfeed is instantly stopped with no over-travel. This U-axis radial position relative to the position of the machine spindle centerline is the automatically sized radius value to be ground in the workpiece and is a datum or preset radial position to which the tool is moved relative to the jig grinder spindle centerline during the grinding mode.
