Abstract
A workpiece centering gauge for a grinding machine includes a link having a first pivot configured to couple with the grinding machine; a first encoder that measures an angle of the link at the first pivot; a second pivot included with the link; a measuring fork configured to releasably contact an outer surface of an elongated workpiece; a surface feeler, having a transducer, included with the measuring fork that measures a workpiece diameter a second encoder that measures an angular position of the link relative to the measuring fork; the angular position measured by the first encoder, the angular position measured by the second encoder, and a measured workpiece diameter are used to determine a deviation of the elongated workpiece from a centerline.

A workpiece centering gauge for a grinding machine, comprising:
- a link having a first pivot configured to couple with the grinding machine;
- a first encoder that measures an angle of the link at the first pivot;
- a second pivot included with the link;
- a measuring fork configured to releasably contact an outer surface of an elongated workpiece;
- a surface feeler, having a transducer, included with the measuring fork that measures a workpiece diameter;
- and
- a second encoder that measures an angular position of the link relative to the measuring fork,
- wherein the angular position measured by the first encoder, the angular position measured by the second encoder, and a measured workpiece diameter are used to determine a deviation of the elongated workpiece from a centerline.
A grinding machine including one or more grinding wheels, comprising:
- a workpiece holder that releasably holds an elongated workpiece and is configured to rotate the elongated workpiece about a longitudinal axis;
- and
- a workpiece centering gauge including:
- a link having a first pivot configured to couple with the grinding machine;
- a first encoder that measures an angle of the link at the first pivot;
- a second pivot included with the link;
- a measuring fork configured to releasably contact an outer surface of a workpiece;
- a transducer included with the measuring fork that measures a workpiece diameter;
- and
- a second encoder that measures an angular position of the link relative to the measuring fork,
- wherein the angular position measured by the first encoder, the angular position measured by the second encoder, and workpiece diameter size are used to determine the deviation of the elongated workpiece from a center.
