PROFILING OF ROTATION TOOLS FOR FORMING OF HELICAL SURFACES

This paper presents a generalized analytical method for profiling of a ll types of rotation tools for forming helical surfaces. The profile d f these surfaces is specified discretely and there are no limits for i ts complexity, variety and determination in a certain section. A mathe matical model is created which determines optimal calculation position providing such a space orientation of the tool at which rational geom etry of the cutting tooth of radial relieved profile milling cutter is obtained. Research is carried out for the influence of the input info rmation of profiling and adjustment of the tool on the accuracy of the helical surface. (C) 1998 Elsevier Science Ltd. All rights reserved.
