摘要
A new testing device has been developed to investigate the mechanism of friction and lubrication in the deep-drawing process. The frictional force occurring in the flange part of the cup was measured directly. The relevant factors likely to affect the frictional resistance at the tool-metal interface include the clamping force, the drawing speed and the viscosity of the lubricant. One additional factor related to the frictional behaviour is the characteristics of a lubricating layer in the flange area. The mechanisms can be assessed by examining optical micrographs of the worn surface and the variation in the surface roughness on the flange during the deep-drawing process.
