Description:

This application is a continuation-in-part of U.S. Pat. application Ser. No. 776,389, entitled, "Method and Apparatus Including a Gauge for Positioning a Numerically Controlled Machine" and filed on Nov. 18, 1968.

Abstract:

In a machine tool, a calibration and gauging system comprising drive means for moving a tool or inspection probe to a commanded position which is beyond a calibration position. The calibration and gauging system also includes circuitry for developing a transfer signal when the tool or inspection probe has arrived at the commanded position and a "false" transfer signal when the tool or probe has arrived at the calibration position. The transfer signals initiate the next sequence of the machine tool program.
