STUDY ON FRICTION IN SHEET METAL FORMING USING A NEW FRICTION TEST METHOD

Abstract

Abstract: The change of friction coefficients between deformed press and die during sheet metalforming were tested by using a new kinds of friction test device. The tested sheet materials are 08Al, IF steel coated IF steel, and different thickness of sheets. Friction coefficients of deformed sheets for different lubrication condition, Punch form and surface state of Sheets were measured. The results show that the friction coefficients of deformed sheets is extremely influenced by lubrication and Punch form.

Key words: Forming, Friction coefficients, Lubrication, Sheet metal, Steel sheets
