| Abstract: | This paper presents an algorithm for computing the form of helical or spur gear fillets on a digital computer. These types of tools are considered to generate the fillet: rack-type tool (hob, rack cutter, or grinding wheel) with or without a protruberance, shaper cutter, and shaving tool. Formulae for the coordinates of the fillet are derived and the boundary points of the fillet are determined both for non-undercut and undercut gearing. Flow diagrams for the solution of some difficult problems are given. |
