Abstract

A grinder for form grinding gear teeth in which a work gear is positioned rotationally by a computer controlled drive. A sensitive probe in known angular relation to a grinding wheel about the axis of the gear is positioned at random in any tooth space in each of a series of probing operations carried out at a plurality of spaced points along the length of a tooth space. In the probing operation at each point, the probe senses the angular positions of the gear when the gear is driven in opposite directions into probe actuating positions of adjacent tooth surfaces and the computer computes one half of the angular difference between the two angular positions. The computer then averages the one half angular difference computed at each of the plurality of spaced points to provide a stock divided grinding position. The gear may then be rotated to the stock divided position for grinding.
