Formalized description and synthesis of schemes for shaping helical flights and auger billets based on the componentic methods

Abstract

Based on the use of the componetic methods the universal method for the formalized description of the ways of shaping the helical flights and auger billets, obtained by different technological methods, has been developed. The method takes into account the number, composition and direction of shaping and auxiliary movements of the executive bodies in the coordinate system of technological equipment, the design features (shape) and direction of movements of the sections of the initial workpiece and the principle of its transformation to the spiral form, also the composition and direction of movements of the working surfaces of shaping tools. The results obtained can be used for the synthesis of new progressive schemes for shaping of helical flight and auger billets.
