ABSTRACT:
A system and method for controlling operation of a machine tool such as a grinder wherein engagement of the machine tool with a workpiece is controlled in real time by a workpiece measurement signal from a gage likewise engaged with the workpiece. The measurement gage is periodically brought into measuring engagement with a gage master having a predetermined master dimension relative to the desired machined size of the workpiece. The resulting gage master measurement signal is compared with a reference, and a compensation signal is generated and stored as a function of the magnitude and polarity of any departure from the gage master measurement signal from the gage master reference signal. Thereafter, during the machining mode of operation, motion of the machine tool is controlled as a combined function of the workpiece measurement signal and the compensation signal generated and stored during the calibration mode of operation.
