Development of an Automated Shaft Outside Diameter Measuring System

To meet tight tolerance requirements of mass produced shafts which are subcomponents of automobile parts, an automated measuring system has been developed. The system comprises of a non-contact shaft diameter measuring instrument using laser, a feed mechanism of a step motor and ball screw and a personal computer. The system can determine pass-fail of the piece under test and also analyze data for statistical process control.
