      Tribology
      Oral Presentation

      To improve the accuracy of forming simulations advanced friction models are increasingly used in industry. These models account for the physical properties of the sheet, tool and lubrication and describe the tribological conditions during the forming operation. One of the main influencing factors on the tribology system, and therefore the friction coefficient, is the surface roughness of the...

    2. 92. Experimental investigation of the effect of lubricant change on automotive component

      Tribology
      Oral Presentation

      Manufacturing problems resulting from lubricant supplier changes are relatively common in automotive press shops. Computer-aided processes and tool design detect a significant proportion of manufacturing noises before tools are physically produced. In modern forming codes, an enhanced Coulomb model is used to numerically model the friction phenomena associated with lubrication. In laboratory...
