The CEL Method as an Alternative to the Current Modelling Approaches for Ti6Al4V Orthogonal Cutting Simulation
(Elsevier B.V., 2017)
The finite element approach is often adopted to study the machining process. The Lagrangian and Eulerian formulations or even Arbitrary Eulerian-Lagrangian (ALE), one of their combinations, are the most employed in the ...
Experimental and FEM analysis of surface integrity when broaching Ti64
(Elsevier, 2018)
The performance of aeronautic critical components is strongly dependent on its fatigue behavior, which is directly linked to their surface integrity condition. Broaching operation is a machining operation extensively used ...
Effect of cutting speed on the surface integrity of face milled 7050-T7451 aluminium workpieces
(Elsevier Ltd., 2018)
The guarantee of surface integrity has become a primary objective for researchers when analysing the reliability of machined aircraft aluminium alloy structural parts in high-speed machining. This work studies the effect ...
An analytical approach to calculate stress concentration factors of machined surfaces
(Elsevier Ltd., 2021)
Machining operations affect the properties of the final surface layer, and these can impact on its functional per- formance, particularly on fatigue behaviour. Among the properties of the machined surface, surface topography ...
Surface Integrity When Machining Inconel 718 Using Conventional Lubrication and Carbon Dioxide Coolant
(Elsevier Ltd., 2020)
Surface integrity induced by machining process affects strongly the performance of functional products, for instance, the fatigue life as well as the resistance to stress corrosion cracking. Consequently, it is relevant ...
A comparative study of residual stress profiles on Inconel 718 induced by dry face turning
(Elsevier, 2011)
Residual stress profiles induced by different dry face turning conditions are compared employing X-ray diffraction method, Hole-Drilling method and Finite Element Modelling. It is well known that the surface integrity ...
Evolution of residual stresses induced by machining in a Nickel based alloy under static loading at room temperature
(Elsevier, 2014)
Tensile residual stresses are very often generated on the surface when machining nickel alloys. In order to determine their influence on the final mechanical behaviour of the component residual stress stability should be ...
Influence of tool wear on residual stresses when turning Inconel 718
(Elsevier, 2016)
This paper analyzes the effect of tool wear on residual stresses when turning. Inconel 718 discs were machined for prolonged periods at several cutting speeds, feed-rates and depth of cut. Tests were interrupted to measure ...
Effect of innovative finishing operations on the tribological performance of steel 27MnCr5
(Elsevier Ltd., 2022)
Transmission shafts used in the automotive sector must have a good tribological performance, and therefore an enhanced surface integrity. This paper aims to study the effect of eco-friendly innovative finishing operations ...
Enhancing surface integrity of A7050-T7451 aluminium alloy by pneumatic machine hammer peening
(Elsevier Ltd., 2022)
Aerostructures withstand cyclic mechanical loads and therefore, their design must fulfil surface integrity and fatigue strength requirements. This paper studies the effect of pneumatic machine hammer peening on surface ...
