GEAR-RACK TOOL FOR GENERATING AN INVOLUTE FLANK. VIRTUAL POLE METHOD

Abstract

In the paper, an approach to the issue of gear-rack type tool profiling is proposed, based on the “virtual pole” method. The proposed issue has also been solved based on complementary fundamental theorems, but the virtual pole method has the advantage of a simplified form of writing the generating movements. This makes it possible to avoid the need to write the relative movements between the tool and the piece.The paper presents the application of the virtual pole method for generating an involute profile.
