متن کاملSurface roughness and dry friction.
Persson's multiscale contact mechanics theory combined with a multiscale Brillouin-Prandtl-Tomlinson model is used to show that on the basis of these models "dry friction" [i.e., kinetic friction that remains at exceedingly small velocities (but still above the creep range) close to its value at higher velocities] should almost always occur for self-affine surfaces when the dominant interaction...
متن کاملInfluence of machining parameters on surface roughness and dry friction
Article history: Received 6 October, 2015 Accepted 7 March 2016 Available online 8 March 2016 Dry friction depends on the surface topography which, in turn, is governed by machining parameters in addition to several other factors,. Therefore, in order to establish a qualitative relationship among these factors, the surface roughness and coefficient of static friction are measured for specimens ...
متن کاملEffect of Cutting Parameters on Tool Wear, Surface Roughness and Material Removal Rate During Dry Turning of EN-31 Steel
ISBN 978-93-82338-21-5 | © 2012 Bonfring Abstract--The present paper is an experimental study to investigate the effect of cutting parameters (cutting speed, depth of cut and feed) on tool wear, surface roughness and material removal rate (MRR) during dry turning of EN-31 steel. Turning experiments were conducted with cutting speeds: 250, 300, 350 m/min, feeds: 0.15, 0.2, 0.25 mm/rev and depth ...
متن کاملAnalysis of Surface Roughness and Material Removal Rate in Dry and Cryogenic Machining of En31 Steel
Production rates play important role in the turnover of any industry. In order to increase the production rates, industrial processes are need to be speedup by speeding input parameters such as cutting speeds, feed rates etc. But with the higher speeds and feeds the heat generation also increases between tool-chip, tool and work piece interfaces, which reduce the tool life, product quality and ...
متن کاملThe Effect of Surface Roughness on the Fretting Corrosion of 316l Stainless Steel Biomaterial Surfaces
The medical device industry is still seeking answers to the mechanically-assisted corrosion (MAC) problem, which becomes increasingly important due to modularity in design. MAC manifests in various forms, some of which are fretting corrosion, crevice corrosion and stress corrosion. Several studies have been conducted to understand the causes and the factors that affect fretting corrosion. Some ...
