Abstract This work deals with the development of a new tribometer designed for characterisation frictional properties at tool/chip/workpiece interfaces in cutting processes. Based on plane–sphere contact configuration, experimental set‐up enables continuous regeneration pin–workmaterial contact. The average pressure can be selected up to 3 GPa under sliding velocities reaching 16 m/s. Under such severe conditions, which are not reachable conventional tribometers, apparent friction...
Abstract This paper aims at characterizing the frictional behaviour cutting tool-workmaterial interface during dry machining of a Inconel 718 in its aged state with various coated carbide tools and c-BN tools. A specially designed open tribometer has been used to characterize friction coefficient, heat partition coefficient under extreme conditions corresponding ones occurring cutting. The provides evolution apparent for large range sliding velocity contact pressure. It shown that as well...
This work deals with the identification of a new friction model for high speed dry cutting AISI4142 steel TiN coated carbide tools. Both experimental and numerical studies were used to find relationship between coefficient, sliding velocity, contact pressure temperature. A tribometer, based on plane-sphere configuration, has been developed reach extreme conditions similar ones occurring during metal cutting. The apparent provided by ratio tangential normal forces, is measured. It assumed...
Purpose The aim of this work is to check the influence some sewing parameters upon tensile behaviour a textile assembly (assembly two woven samples by seam). Design/methodology/approach This analysis was carried out according approach “experimental design”. studied are thread, stitch type, density, needle size and edge seam. targeted answers drawn from test on assembly: breaking strength, elongation deformation energy. Findings In order highlight seam, load‐extension curve for line...
The characterization of frictional phenomena at the tool-chip-workpiece interface in metal cutting remains a challenge. This paper aims identifying friction model and heat partition this during dry an AISI1045 steel with TiN coated carbide tools. A new tribometer, based on modified pin-on-ring system, has been used order to reach relevant values pressures, temperatures, sliding velocities. Additionally 3D Arbitrary Lagrangian Eulerian (A.L.E.) numerical simulating test developed extract...
In this paper, an orthotropic hyperelastic model of woven fabric has been developed. The is coded in Abaqus/Explicit using subroutine Vumat. work reported here covers the influence ratio between shearing and tensile rigidities on stress strain fields. Numerical results from bias extension tests samples three aspect ratios are compared to those predict by theory. This study proved that deformation depends not only specimen dimensions but also fabric.
Tensile tests are applied on fabric in seven directions oriented with 15° increment respect to the warp direction. These carried out articulated jaws ensure their homogeneity. In addition measuring stress and displacement fields, a strain optic analysis by videos acquisition processing is implemented. An of anisotropy degree homogeneity fields presented. A linear elastic orthotropic model identified particular zone tensile curves. numerical finite elements method has been compared...
