Tangents method to profile rack-tools to generate by wrapping

Abstract

Modelling surfaces generated by wrapping, by using the rolling method, supposes to know a rack-tool profile numerical model together to a specific algorithm to study the enwrapped of a profiles family discretely expressed. On this way, a specific algorithm – “Tangents Method” – was created, in order to allow enwrapped surfaces (profiles) study, when profile to be generated is discretely represented. The quality of this method was proved by comparing the results from its application to the solutions given by already known methods. Examples when generating by using a rack-tool an elementary profile (a straight line segment) are presented. The results obtained show the quality of suggested algorithm to study enwrapped profiles associated to a couple of rolling centrods.
