Algorithm for Corrective Profiling of Rack-Gear Tools

Résumé

Is presented a mathematical model, starting from a virtual generatrix of the surface to be generated, and, based on this, an algorithm for
corrective profiling of rack-gear tool, in order to increase the machining precision at generation by rolling of this tools type.
We accept that the surfaces to be generated, the target surfaces, are effective measured surfaces and are expressed in numerical form. Is
imagined a model for the approximation of the corrected rack tool’s profile by the back face form’s changing regarding the standard form – the approximated profile. It was elaborated a software for this model and are presented numerical examples.
