Solid contacts involving soft materials are important in mechanical engineering or biomechanics. Experimentally, such have been shown to shrink significantly under shear, an effect which is usually explained using adhesion models. Here we show that quantitative agreement with recent high-load experiments can be obtained, no adjustable parameter, a non-adhesive model, provided finite deformations taken into account. Analysis of the model uncovers basic mechanisms underlying shear-induced area...
In machining, tool temperatures and thus wear are significantly influenced by frictional behaviour. Friction tests used to determine the friction coefficient depending on relative speed, which serves as basis for parameterising models input data chip formation simulations. Therefore, this paper represents investigations towards behaviour of uncoated coated (TiN, TiAlN) carbide tools when using two different movements (translational rotary) cooling lubricant conditions. dry conditions, show...
Hot stamping is characterised by severe contact conditions, especially when forming aluminium components. In order to improve the tool lifetime, process economy, and component quality, understanding initiation mechanisms behind transfer onto surface at high temperatures critical. To date, tribological interaction between tools sheets temperature has received limited attention. Lubricants, combined with engineering techniques (e.g. coatings, nitriding topography control), show great potential...
During a machining operation, the tool tip is subjected to elevated interface temperatures and contact pressures. A considerable improvement can be achieved through an appropriate selection application of cutting fluid. Although many technologies attempt reduce their use move cleaner production, they are still widely employed in industry. Under such severe conditions, it necessary understand exact contribution from tribological point view order optimize use. The aim this study evaluate...
Abstract Aluminium alloys are commonly used as lightweight materials in the automotive industry. This non-ferrous family of metallic offers a high versatility properties and designs. To reduce weight improve safety, strength-to-weight ratio (e.g. 6XXX 7XXX), increasingly implemented vehicles. However, these exhibit low formability experience considerable springback during cold forming, therefore hot formed. During severe adhesion (i.e. galling) aluminium onto die surface takes place....
Tribological systems working under severe conditions like high pressures, sliding velocities and temperatures are subjected to different phenomena such as wear, oxidation changes in mechanical properties. In many cases, there several mechanisms occurring simultaneously. The predominating type(s) of wear mechanism(s) presented will depend on the materials contact, operating parameters surrounding environment. this work, temperature tribological studies boron steel against tool were conducted...
Sustainable manufacturing trends dictate the need for cleaner processes that are environmentally benign and with no adverse health effects. Cryogenic machining in recent times has emerged as such an effective clean process. In this field, a strong collaboration among partnering researches EU US been established. Prior research proven cooling effect sustainable operation is significant, while lubrication still either marginal or questionable. The nitrogen phase delivered to cutting zone...
Finish turning is one of the key operations governing residual stresses below machined surface. The stress state depends on cutting conditions and selected tool system, i.e. macro geometry, edge preparation as well grade. However, wear often affects interaction between workpiece leading to severe modifications state. This work aims at investigating influence surface integrity in longitudinal a 15-5PH stainless steel. First, an experimental sensitivity study performed assess effect various...
