GRAPHICAL METHOD IN CATIA ENVIRONMENT FOR PROFILING ROTATING CUTTERS
Journal Title: Proceedings in Manufacturing Systems - Year 2014, Vol 9, Issue 2
Abstract
In this paper, we present a graphical method, developed in CATIA environment, based on the method of substituting circles family and dedicated to profiling rotating cutters. Hereby, the family of substituting circles associated with the worked piece (the profile to be generated) is determined at the same time to the curve transposed, in the rolling motion, to the tool centrod. After finding the position of the contact points between the generated profile and the family circles, we can determine, in the transposed family, the locus of the points from the reciprocal enwrapping profile – the rotating cutter profile. The paper also includes a method application for generating the helical surface of a ball screw, and a comparison between the profiling results when using the graphical method, versus an analytical method. The results prove the coincidence between the two profiles determined as above, on one hand, and both rapidity and precision of the graphical method, on the other hand.
