This article introduces a method to calculate contours of form cutters for machining helical gears from given gear tooth profiles. It is essential to find a relationship between the cutter contour and the gear profile in order to carry out the calculation. The method introduced in this article uses contact points between the cutter rotary surface and the gear tooth surface to establish the relationship. A minimum distance principle is applied. Equations for the calculation are derived and an example is given.
