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 ...
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 ...
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 ...
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 ...
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 ...
Reduction of distortions in large aluminium parts by controlling machining-induced residual stresses
(Springer, 2018)
Large aluminium monolithic parts used in the aeronautic industry frequently show significant geometric distortions after the machining process. These distortions are the consequence of the initial residual stresses of the ...
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 ...
