A study was conducted to investigate the frictional behavior of metals in hot metal deformation. The purpose of the study was to gain a better understanding of friction at high pressures and temperatures characteristic of metal-working processes. A test technique was developed in which a thin foil was compressed between a hardened anvil and a flat plate. Friction was determined by applying a tangential force to one of the specimens. A technique was also developed to evaluate lubricants based upon the surface deformation they would withstand. These techniques were used to measure the coefficient of friction and surface damage of various pure metals and alloys in both the lubricated and the unlubricated condition, at temperatures to 1800 F and pressures to 200,000 psi. It was found that this test uniquely yielded the friction coefficient of a given metal combination at a particular pressure and interface temperature. The variables found to be most significant in the pressure range 8000 to 200,000 psi are the roughness, temperature, surface oxide, and tool materials. Over this pressure range, friction is primarily determined by the strength of the metal. Adhesion effects modify the friction but primarily determine the extent of metal transfer.

Although the problem of tool design - involving both the selection of suitable geometry and material- has exercised the attention of metal forming engineers for as long as this industrial activity has existed, the approach to its solution has been generally that of the 'trial and error' variety. It is only relatively recently that the continuing expansion of the bulk metal-forming industry, combined with an increase in the degree of sophistication required of its products and processes, has focussed attention on the problem of optimisation of tool design. This, in turn, produced a considerable expansion of theoretical and practical investi gations of the existing methods, techniques r,nd concepts, and helped to systematise our thinking and ideas in this area of engineering activity. In the virtual absence, so far, of a single, encyclopaedic, but sufficien tly deep, summation of the state of the art, a group of engineers and materials scientists felt that an opportune moment had arrived to try and produce, concisely, answers to many tool designers' dilemmas. This book attempts to set, in perspective, the existing - and proven - concepts of design, to show their respective advantages and weaknesses and to indicate how they should be applied to the individual main forming processes of rolling, drawing, extrusion and forging.

This classic work, originally published in 1950, was a landmark in the development of the subject of tribology. When it was first published, one reviewer wrote that it 'marks the beginning of a new epoch in the study of friction and lubrication .... The most interesting and comprehensive work on a single branch of physics I have ever read.' For the 1986 reprint David Tabor wrote a new preface, reviewing developments in the subject in the 36 years since the book first appeared. He has also added an appreciation of the life and work of F.P. Bowden, who died in 1968.
