STUDY ON INFLUENCE OF PROCESS PARAMETERS ON DEFORMATION ABILITY IN COMBINED EXTRUSION FROM HIGH-STRENGTH ALUMINIUM ALLOY

Abstract

This paper presents the results of a study on the influence of process
parameters on the deformation ability for axial symmetry detail from high-
strength aluminum alloy by the combined extrusion method. The Deform 3D
software is used in numerical simulation. The process parameters studied include
machining speed (v), die radius (rc), and coefficient of friction (µ). The deformation
ability is evaluated through the die filling factor η and the maximum forming force
Pcn (Tons). The obtained results allow analysis and selection of reasonable process
parameter ranges of the forming process, serving to manufacture details in
defense and industry.
