Abstract
The Michigan Tech sheet metal strip test apparatus with controllable drawbead penetration simultaneously performs two different tests for friction coefficient. The flat binder coefficient of friction and die shoulder coefficient of friction are complex functions of sheet tension, surface topography, lubrication, and sliding distance. The average coefficient of friction for the drawbead and blankholder region at maximum drawbead penetration can be predicted by taking the average of the binder coefficient of friction and the die shoulder coefficient of friction.
