Examination for post-sharpening adjustment of cutting edge of a worm gear hob with circle arched profile in axial section

Abstract

A necessary condition of intelligent manufacturing is the continuous development of tool geometry. One relevant element of tool geometry is the analysis of the relationship between edge geometry and manufactured surface quality. During the production of worm gear, in order to achieve the required quality, the worm gear hob must be continuously tested for wear and the cutting edge must be re-sharpened, which results in a decrease in the diameter of the hob. Changes in geometric conditions resulted from the increase in distance between the re-sharped hob axis and the gear axis. The subject of this paper is the analysis of manufacturing with a reduced distance between the worm gear and the worm gear hob due to re-sharpening of the cutting edge of the tool and the fit of the drive.
