Technical Examples

An apparatus is provided for centering a workpiece on a machine tool that includes first and second guide plates having respective first and second aligned bores therein for supporting a centering pin mounted therein for axial movement between a retracted position and a use position. The centering pin cooperates with a workpiece such as a fan rotor blade of a turbine engine for positioning the workpiece in a predetermined position relative to a metal shaping operation to be carried out by the machine on the workpiece. At least one spring cooperates with the centering pin for exerting a predetermined axial bias for urging the centering pin into the use position. A lock locks the centering pin in the use position.
