Manufacturing Perspective in the Design of Bevel Gearing,

This paper describes an advanced designproduction technique for the in-process inspection and manufacture of aircraft quality spiral level gearing. The technique involves mapping of spiral teeth over their entire working surfaces using the Zeiss Model UMM 500 universal coordinate measuring machine and quantitatively comparing surface normals with the nominal master gear values at some 45 grid points. In addition, this technique features a means for rapidly calculating corrective grinding machine setting changes for controlling the tooth profile geometry within specified tolerance requirements.
