THE VIRTUAL POLE METHOD –AN ALTERNATIVE METHOD FOR PROFILING TOOLS WHICH GENERATE BY ENWRAPPING

Résumé

In the paper is presented a method for profiling of tools that generate by enwrapping, by the rolling method, curls ordered by surfaces. By the new method is intended to eliminate one of the main disadvantages associated with the processing by generating of parts with radial symmetry, namely the difficulty related to the calculation of generating tool profile. The method allows eliminating the need to determine analytically the relative movement between the tool and the blank, which simplifies the calculation mode.
