The profiling of the abrasive tools for the continuous sharpening of hobbing cutters with shifted teeth

Résumé

In this paper, are presented simplified methods for the profiling of the second-order tools used for the continuous generation of the back surfaces of the worm hob with shifted teeth. The solving of the technical problems related to the profiling of the abrasive tools used for the continuous generation of the back surfaces of the worm tool’s teeth has led to the replacement of the theoretical second-order tool with a ruled revolution surface. The technological solutions for the approximation of the suggested abrasive tools’ profile, of disc or end mill type, show the fact that the size of the approximation error is very small and can be technically accepted.
