Cup drawing tests were performed to evaluate the friction characteristics of sheet metals.<br/> The 1 inear relationship between drawing force and blank holding force obtained from the cup drawing test was used to calculate the coefficient of friction of the sheet metal.<br/> The friction coefficient was compared to that from conventional<br/> draw bead friction test,<br/> It was clarified that the cup drawing test can be used as a<br/> simple and convenient method for evaluating the friction characteristic of the sheet metal and also lubricity of the lubricant used.<br/> Key words: Stamping formability, Sheet metal, Cup drawing test. Coefficient of friction, Draw bead friction test, Lubricant<br/>
