Abstract
An optically coupled in-process gaging system is disclosed for use with numerically controlled machine tools wherein a battery-powered gage unit is enclosed in a housing adapted for retention in an automatic NC program controlled selection from the NC tool magazine. The gage unit can be placed in a machine tool device, such as a spindle, whose movement is directed by the NC program to place a gage transducer of the gage unit in contact with a workpiece to perform dimensional gaging. The gage unit converts an electrical transducer signal into an infra-red optical FM signal for wireless transmission to a receiver unit coupled to a microcomputer-based control unit.
