Machining of cylindrical tooth-wheels by hyperbola cutting tools

Abstract

The article investigates cutting of cylindrical tooth wheels using multi-passing hyperbola instrument. The instrument is produced as an enveloping a tooth wheel being machined one. Hyperbola cutters are obtained in a space machine-tool engagement. A principally new scheme of the instrument form shaping has been developed for tooth cutting instrument production. At this, a conventional gear machining equipment has been used. Major geometric and kinematic parameters of tooth cutting using the developed instrument have been defined in an analytical form. Main instrument surface as well as contact lines on the surfaces being machined have been defined. Main elements of a machine-tool contact of a hyperbola instrument with a work-piece being cut have been defined. The developed instrument may be used in all spheres of machine-building.
