Graphical method in autocad for profiling tools for generation of helical surfaces

Résumé

The profiling of tools bounded by revolution surfaces for generating helical surfaces may be solved calling the basic theorems of surface enveloping or calling
complementary methods. In this paper a method developed in the AutoCAD design environment is proposed. The method is based on the specific theorem of the
“substituting circles family” for profiling end mill which generates a helical surface with constant pitch.
