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 ...
Machining behaviour of Ti-6Al-4V and Ti-5553 alloys in interrupted cutting with PVD coated cemented carbide
(Elsevier, 2012)
Machining behaviour of Ti-5553, Ti-6Al-4 V mill-annealed (MA) and Ti-6Al-4 V solution treated and aged (STA) alloys was studied in different interrupted cutting operations using PVD coated cemented carbide tools. Single ...
Numerical Simulation of Surface Modification During Machining of Nickel-based Superalloy
(Elsevier, 2015)
The main objective of this study is to implement a reliable FE model of the orthogonal machining of a Nickel based superalloy for the prediction of microstructural changes occurring during the process. A FE numerical model ...
Simulation of distortion due to machining of thin-walled components
(Elsevier, 2013)
The distortion of components is strongly related to the residual stress state induced by manufacturing processes like heat treatment, forming or machining. Each process step affects the initial stress state of the following ...
Surface machining condition and fatigue life on Inconel 718
(Elsevier, 2018)
Life assessment of components working in aero-engines at elevated temperatures is critical. Machining has a serious effect on these nickel-based alloys, for example in turbine discs, affecting their life in service. Machining ...
Broaching: Cutting tools and machine tools for manufacturing high quality features in components
(Elsevier Ltd., 2020)
Broaching is a unique machining process with high accuracy and surface quality, which is employed in massand batch production for the manufacture of components with highly complex geometries. It involves the use of ...
Effect of surface integrity generated by machining on isothermal low cycle fatigue performance of Inconel 718
(Elsevier Ltd., 2022)
Critical aero-engine components such as turbine discs must withstand severe cyclic stresses, which can eventually lead to low cycle fatigue (LCF) failures. These components are made of difficult-to-cut alloys and machining ...
Surface topography irregularities generated by broaching
(Elsevier Ltd., 2022)
Surface topography irregularities generated by broaching are analysed. Experimental tests were carried out on three workpiece materials: AISI 1045, Ti-6Al-4V, and Inconel 718, varying the cutting speed, rise per tooth, and ...
