Enwrapping surfaces with point contact — comparisson between catia method and analitical one
Abstract
In this paper, is made the comparison between the profiles of the worm tool, which generates a polygonal shaft, obtained by a classical analytical method and the graphical method developed in the CATIA design environment. The comparison is made in order to determine the quality of the profiling method of tools which generate, by point contact, ordered curls of surfaces. The form of the intermediate surface (the generating rack-gear) and the form of characteristic curves are presented in graphical form, and the form of axial profiles of the worm mill calculated by the two methods is presented in numerical form.
