Shaping the Helical Surface by the Hobbing Method

The shaping of a helical surface using a rotary tool with an arbitrary tool action surface axial profile has been discussed. Disc, ring, finger and cup-type tools were included in the computation program. The reverse task, where the arbitrary worm surface profile is given, was solved for the case of helical surface machining with a finger-type tool by the step-by-step method.
