The part is positioned in the ã test station on top of three carbide rods that allow the part to rotate. An idler wheel is pneumati- ã cally operated from the inside of the dial forcing the part against two polyurethane coated drive wheels that cause the part to rotate. The OD probe is located be- ã tween the drive rolls and is on a driven precision slide that scans the part OD. ã The Eddy Current probe is connected to a STATOGRAPH ECM that monitors background signals to verify operation, rotation and the reject limit that signals the ƒP aw. ã A Clearance Compensation Card is included to automatically adjust the sensitivity of the STATOGRAPH ECM for variations in the air gap or lift-off. ã At the completion of the test, the rotation is stopped and the part released for index If the part is accepted, it is pushed from the dial by a pneumatic arm into the exit ã track. ã If the part is rejected, it is unloaded at the reject station onto the reject track.
