PURPOSE: To dispense with the trial working for correcting the inter-axis distance even when a dress gear has errors on manufacturing, to easily and efficiently transfer the tooth form of high accuracy of the dress gear to a work, and to facilitate the modification and recycling of the dress gear.
CONSTITUTION: The inter-axis distance of an internal gear type grinding wheel 5 and a dress gear 4 is the value of the difference between the design tooth thickness of the dress gear and the measured tooth thickness divided by twice the sine of the design operating pressure angle added to the design inter-axis distance, the axis cross angle 7 is the value of the difference between the design tooth thickness of the dress gear and the measured tooth thickness multiplied by the correction factor obtained by calculation in advance added by the design axis cross angle for the dressing, and then, the axis cross angle 7 and the inter- axis distance between the internal gear type grinding wheel 5 and the work 3 are the design axis cross angle and the design inter-axis distance for the working.
