TITLE
A Study of Radial Gear Extrusion

ABSTRACT
In recent time manufacturing of gears and gear-like components by metal forming operations has been under intensive growth. The gears manufactured by metal forming demonstrate improved cost effectiveness and higher mechanical properties compared with gears made by conventional metal cutting methods. In this paper cold radial extrusion of gear-like components has been investigated theoretically and experimentally. Three different teeth-geometries have been analyzed: with radial, parallel and tapered flank profile. An upper bound approach has been used to develop mathematical model to predict the main process parameters: total power, deformation force and average pressure. Experimental work with aluminum workpieces has been conducted in order to verify the results obtained by the upper bound analysis.
