Comparison between the CAD method and the analytical method -rotary cutter tool’s profiling-

Abstract

This paper is concerned with a CAD method, developed in the CATIA design software for the tool profiling, generated by enwrapping, for the rotary cutter tool, in particular. The method is based on the creation of a virtual mechanism which keeps the rolling condition of centrodes associated with enveloping profiles, making sure that both the tool profile and the blank profile meet one of the fundamentals theorems of gearing. An algorithm was elaborated, alongside with specialized software, in the CATIA design environment, for the determination of the rotary cutter generation method. The present paper deals with the numerical validation of the results, relying on a unanimously accepted analytical method. Application examples are presented for simple analytical profiles.
