4 steps to quickly simulate your metal forming process

    1. Study of Friction during Forging OperationAbstractThis paper presents a review on the effect of friction during forging operation; must especially the double cup extrusion process. The metal forming process, such as forging, is one of the manufacturing processes where metal is pressed or forced A study on the influences of CoulombAmontons and Nov 20, 2014 · Joun et al. studied the effects of friction laws on metal forming processes such as strip rolling, ring gear forging, multistep extrusion, and pipe shrinkage and expansion. They indicated that considerable differences exist between the constant shear and Coulomb friction laws, especially in friction-sensitive metal forming processes.

      Sep 05, 2018 · Effect of friction laws on metal forming simulations A summary [2/2] Effect of friction laws on metal forming simulations A summary [2/2] In the previous article, effect of two friction formulations on three processes namely cylinder compression process with low aspect and contact ratio, cylinder compression process with high aspect and contact ratio and the hot strip rolling Galling phenomena in metal forming SpringerLinkNov 13, 2020 · Galling phenomena in metal forming not only affect the quality of the engineered surfaces but also the success or failure of the manufacturing operation itself. This paper reviews the different galling conditions in sheet and bulk metal forming processes along with their evolution and the effects of temperature on galling. A group of anti-galling methods employed to prevent galling defects Modeling of the Friction Behavior in Metal Forming Process Oct 01, 2015 · In various plastic forming processes of metals, friction has been revealed to play an important role in the determination of the material flow, fracture, and surface quality. The precise description of friction behavior is thus a critical issue for the accurate prediction and analysis of these formability indicators.

      Numerical study of the friction effects on the metal flow

      Apr 09, 2013 · Friction plays an important role in bulk metal-forming process. Especially, it has an important influence on metal flow in the local loading process. In the present study, the influence of friction on the metal flow in local loading forming process of rib-web component was analyzed by using analytical method, numerical simulation, and experiment. Variation of the friction conditions in cold ring This study shows that during the cold compression processing of #45 (AISI 1045) steel rings, the magnitude of friction and surface roughness (R a) changes Effect of friction laws on metal forming simulations A Sep 03, 2019 · Effect of friction laws on metal forming simulations A summary [2/2] In the previous article, effect of two friction formulations on three processes namely cylinder compression process with low aspect and contact ratio, cylinder compression process with high aspect and contact ratio and the hot strip rolling process were presented.
