Corrective profiling method for tools that generate by enwrapping

Abstract

There are known methods of corrective profiling of tools, which can predict the quality of parts generating obtained with cutting tools that process by enwrapping. The purpose of this profiling is to avoid errors caused by improper profiles of generating tools, using the so-called method of "reverse generation", which is based on the reproduction of the relative movement between the tool and the part, but in which the tool profile is known, and the goal is determining the part’s profile. The method presented in this paper uses the "virtual pole" method to profile the tools generating by enwrapping, by the rolling method and avoids the need to explicitly write the enveloping condition. This paper demonstrates the possibility of applying this method to the profiling of gear-shaped tools and presents the application of the proposed algorithm for a tool whose profile was determined directly by measurement. The numerical application developed demonstrates the ability of the method to simply solve the problems related to the corrective profiling of the tools that generate by rolling.
