Profiling methodology for side mill tools for generation of helical compresor rotor using reverse engineering

Abstract

In this paper it is presented the issue of profiling tools bounded by revolution primary peripheral surfaces, side mill tool and end mill tool, for generation of the gap between the lobes of the helical rotor. The determination of the rotor form was done by measuring on the MicroHite 3D coordinate measuring machine, with precision of 0.001. Using the capabilities of the CATIA design environment, methods for the determination of the worm’s profile and side mill profiling (or end mill tool for generation of the gap between two successive teeth) were elaborated. They are presented the axial profiles of the tool, in numerical and graphical form.
