The Method of Design and Manufacturing of the Gear Hobbing Cutter with Bulges

This paper presents the design and manufacturing aspects of these tools. Constructive and geometric peculiarities are exposed for the gear hobbing cutter with large modules. The design of the gear hobbing cutter with modified profile in the parametrized variant permits a rapid adaptation to any conditions. Depending on the particular constructive geometric of the gear hobbing cutter profile it was created the virtual prototype (solid model). This is analyzed and, in the final stage, it is manufactured [1,2,3,4,] . Manufacturing techniques of the tool include the obtaining of the profiled knifes for clearance (achieved by increased 50:1 templates on the machine for profiled tools) and the special control templates (obtained on templates milling machine F. Studer) [. This paper presents the method of obtaining of the gear hobbing cutter profile by adjusting the corresponding shape of the abrasive disc to optimize the grinding conditions [. It is recomended the method which use the changing of the rack reference imposed by technical and functional conditions [7,8,.
