Numerical Analysis of the Forming Process of Head Toothing in Rolling Extrusion on a Shaft from Aluminum Alloy 7075 / Analiza Numeryczna Kształtowania Uzębienia Czołowego W Procesie Przepychania Obrotowego Na Wałku Ze Stopu Aluminium 7075

Abstract

This paper presents the forming method of head toothing with the application of rolling extrusion technology. Tools numerical models were used in numerical calculations. The presented numerical results concern metals flow kinematics, distributions of stresses and strains. Determined in the process technological parameters of head toothing forming allow foreseeing real material flow in the experiment planned for conducting.

Numerical analysis of bevel gear forming

“…Normally in the presented case the material allowances can be limited to 0.3 -0.4 mm. During machining ,due to non continuous contact between cutting blades of tools, in this case these allowances are bigger (usually about 0.8 mm) This allows obtaining better machining conditions, limiting vibrations and increasing lifetime of machining tools [1][2][3][4][5].…”
