Description:

Abstract:

A grinding machine control is provided having a compensation circuit for providing correction signals to modify the point at which a wheelhead infeed cycle is terminated. The correction signals represent varying infeed offset values produced in response to the number of completed infeed cycles following a grinding wheel sharpening operation. The correction signals are derived from a plurality of empirically determined functions relating the number of completed infeed cycles for a particular combination of workpiece and tooling design to deviations of workpiece diameter from a desired dimension.
