2. 1. Wear in sheet metal forming

   Author : Anders Gåård; Pavel Krakhmalev; Jens Bergström; Åsa Kassman; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Sheet metal forming; Galling; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

   Abstract : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of press lubricants, in combination with the introduction of high and ultra-high strength sheet materials, continuously increases the demands of the forming tools. READ MORE
