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 ...
The capacity of statistical features extracted from multiple signals to predict tool wear in the drilling process
(Springer Verlag, 2019)
Industrial processes are being developed under a new scenario based on the digitalisation of manufacturing processes.Through this, it is intended to improve the management of resources, decision-making, ...
Experimental analysis of cutting force reduction during ultrasonic assisted turning of Ti6Al4V
(Elsevier Ltd., 2019)
The machining of difficult-to-cut materials involves limitations leading to low productivity in conventional machining processes due to high cutting forces and tool wear rates. The ultrasonic ...
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 ...
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 ...
Surface Integrity Analysis when Machining Inconel 718 with Conventional and Cryogenic Cooling
(Elsevier, 2016)
Cryogenic machining together with minimum quantity lubrication (MQL), is claimed to be a promising alternative to flood cooling in industrial applications since it avoids the use of large amounts of cutting fluids and it ...
Multi revolution finite element model to predict machining induced residual stresses in Inconel 718
(Elsevier, 2013)
Inconel 718 is commonly used in structural critical components of aircraft engines due to its mechanical thermal properties at high temperatures, which makes it to be considered as a difficult to machine material. In these ...
A sensibility analysis to geometric and cutting conditions using the particle finite element method (PFEM)
(Elsevier, 2013)
The (PFEM) is employed to simulate orthogonal metal cutting of 42CD4 steel. The objectives of this work are mainly three: The first one is to validate PFEM strategies as an efficient tool for numerical simulation of metal ...
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 ...
