Friction behavior of aluminum alloy 3004 sheets in ironing process

Dohda K., Wang Z.

Applied Mechanics and Engineering

1999

Vol. 4, no spec.

133-138

The purpose of this research is to investigate the effect of, ?, the angle between the ironing direction and the rolling direction of the rolled sheets, on the friction behavior in the ironing process of aluminum alloy 3004 sheets under various frictional conditions by changing the viscosity of lubricant, the thickness of lubricant film, working velocity etc.. Experiments showed that the difference in the friction coefficient due to? becomes smaller with increasing viscosity of the lubricant/working velocity or decreasing surface roughness of the rolled sheet. For the lowest viscosity of lubricant in the present experiment, the friction coefficient for ?=0° is about 3 times of the friction coefficient for ?=90°.
