In a companion paper, a friction model for isothermal forging is described. Extension to a general hot forging case requires consideration of heat transfer across the tooling/workpiece interface, since a chilling of the workpiece by the dies will hav

Inspection of 1100-H14 and 5052-0 aluminum alloy surfaces deformed in tension, sheet forming, and rolling with a thick lubricant film indicated that similar mechanisms were involved in the roughening process. The predominant mechanism was associated

A model of a secondary hydrodynamic lubrication mechanism, which is called micro-pool or micro-plasto hydrodynamic lubrication, has been developed. It shows that, with sufficiently high viscosity and sliding speed, the lubricant trapped in the micro-

The authors suggested a boundary friction model which treats the combined influence of surface roughening (due to inhomogeneous deformation) and surface smoothing (due to asperity flattening) on the real area of contact in the presence of plastic str

In the past, many different modes of vibration and causes of rolling chatter have been presented, yet no complete and clear picture of the basic mechanics emerged. In order to control chatter in cold rolling operations, a much better understanding of

The central problem of the analysis and prevention of chatter in rolling operations is in understanding the conditions which lead to dynamic instability. By analogy with metal cutting operations, it appears that a few basic mechanisms may be responsi

This paper presents the development of a new dynamic model of the rolling process which provides estimates of the variations in exit gage, strip speed and tension at entry and exit, rolling force and rolling torque in response to variations in roll s

This paper presents the results of dynamic rolling experiments examining the variations in rolling force, back tension and roll gap in response to a sinusoidal dynamic component of various frequencies being superimposed on the roll gap or back tensio
