Abstract

A new testing device has been developed to investigate the mechanism of friction and lubrication in the deep drawing process. The friction force occurring in the flange part of the cup is measured directly. The friction coefficient associated with the surface texture was assessed by means of eddy-current measurements. The relevant factors likely to affect the frictional resistance at the tool-metal interface include the clamping force, drawing speed, lubricant, and surface roughness. Another of the factors is related to the frictional characteristics of a lubricating layer in the flange area. Evidence for this was obtained by examining the topographic variation of the worn surface during the deep drawing process.
