Abstract
A method and apparatus for gaging the cross-sectional bore diameter generated by an abrading type finishing tool in an abrading machine. The tool and plug gage are mechanically mounted to the same spindle with the plug sized to a predetermined diameter and mounted behind the machining element. The plug gage is indexed to enter the bore being machined at predetermined cycles to determine if an undersize condition of the tool exists. Failure of the plug gage to enter the bore would indicate an undersize condition of the tool and upon the gage entering the bore it would indicate a correct tool size. The invention has further apparatus for shutting down the machine in the event an undersize condition is determined.
