Change Gear Finder for Gear Hobbing (Without Differential)

If a gear hobbing machine is not equipped with differential, there is a fixed relation between index and feed gears and it becomes neccessity to compensate for even slight errors in the index gear ratio, to avoid excessive lead errors.

This program calculates the index and feed gears for gear hobbing without differential. This program modifies the ratio of the feed gears slightly by offsetting the index gear error and thus makes very accurate leads possible.
