Abstract: Grain size and lubricating conditions influence material flow behaviours in micro metal forming processes. In this study, the brass (JIS C) tubes with mm outer diameter and mm inner diameter were treated by annealing at °C, °C and °C to obtain various microstructures with the grain sizes of 20 μm, 34 μm and 80 μm, respectively. Principles of Modern Grinding Technology, Second Edition, provides insights into modern grinding technology based on the author’s 40 years of research and experience in the provides a concise treatment of the principles involved and shows how grinding precision and quality of results can be improved and costs reduced.

The book examines tribology with special emphasis on surface topography, wear of materials and lubrication, and includes dedicated coverage on the fundamentals of micro and nanotribology. The book serves as a valuable reference for academics, tribology and materials researchers, mechanical, physics and materials engineers and professionals in.
The workpiece surface topography is an important factor controlling the mechanisms of lubrication in metal forming processes.
In the present work, the microscopic lubrication mechanisms induced by lubricant trapped in pockets of the surface in strip drawing are by: The results show that the pressure, lubrication conditions, as well as the original topography of specimen have an obvious influence on the surface topography after the experiments, and the.
This chapter deals with the correlations of the tribological behaviour of sheet steel during deep drawing, in particular galling, with surface topography from a 3D point of view. A coherent set of experiments was designed in order to test different steel sheet structures in relation to forming, more specifically galling.
Theoretical models are presented for describing the evolution of pits in the inlet and work zone during cold rolling and strip drawing of shot-blast stainless steel under ‘mixed’ lubrication. Results shows that the rough shot-blast surface is flattened rapidly in a short inlet zone, thereby entrapping the lubricant in surface by: This study explored the influence of the surface topography of a bushing on the lubrication performance of a water-lubricated bearing.
Bushing deformations were considered in the mathematical model. Theoretical calculations and experiments were performed. The test data corresponded well with the simulation.

9 Greyridge Farm Court Stony Point, NY P: () F: () [email protected] Abstract. This chapter presents the main aspects of the tribological systems observed in the most important metal forming processes. Friction, wear and lubrication are discussed in general terms to describe friction models, wear mechanisms and lubrication regimes commonly found in metal forming, which are analyzed for each of the five groups of processes (rolling, extrusion, forging, drawing Cited by: 2.
This lecture aims at gaining an appreciation the importance of friction in sheet metal drawing. It describes the mechanism of friction and lubrication; it shows the importance of surface topography; it aims at learning about factors improving the problem of adhesion and about methods of determining the coefficients of friction in different tribological systems.

B oth hot and cold forging are batch-type processes in which steady-state conditions are never fully achieved and the initial lubricant supply must perform adequately for the duration of the operation.
The lubricant is continuously exposed to changing pressures and velocities, and wear or pickup products in the lubricant also continuously vary, although a dynamic equilibrium may be attained.
