Force Prediction Methodology for Complex Shape Broaching
(Elsevier B.V., 2023)Broaching is widely used for the manufacturing of complex geometries which requires high dimensional accuracy and surface finishing (e.g., fir tree, dovetail). A software development for force prediction in complex shape ... -
Influence of lubrication condition on the surface integrity induced during drag finishing
(Elsevier Ltd, 2020)Tribofinishing is one of the most popular polishing process in industry. The action of small abrasive media around parts enables to reduce significantly surface roughness and at the same time, to induce compressive residual ... -
Influence of Microstructure on Chip Formation when Broaching Ferritic-Pearlitic Steels
(Elsevier B.V., 2017)Broaching is a specific process characterized by relatively low cutting speeds and uncut chip thicknesses. The latter is in the range of 0.1 to 0.25 mm in the roughing section of the tool but can decrease down to 0.0015 ... -
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 ... -
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 ... -
A mechanistic model to predict cutting force on orthogonal machining of Aluminum 7475-T7351 considering the edge radius
(Elsevier B.V., 2019)The ploughing force related with action of edge radius is an important factor which influences flow stress, chip formation or surface integrity. Some fraction of the cutting forces are called parasitic (additional) forces ... -
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 ... -
New design for assembly (DfA) methodology for large and heavy parts assembled on site
(Elsevier Ltd., 2021)A literature review on the assembly design methodologies (DfA) oriented to the assembly of large and heavy parts, reveals the need to develop a DfA methodology. In addition, the lack of DfA evaluation methods for on-site ... -
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 ... -
Opportunities and incentives for Remanufacturing in the Basque Country
(Elsevier B.V., 2018)Remanufacturing is a business model that helps the development of the circular economy. There are numerous successful examples of remanufactured products in different industrial sectors of Europe and US. Obtaining the ... -
Personalised Trachea Stent Designer: a Knowledge Feature
(Elsevier, 2012)Modelling of anatomical parts is usually tackled through triangulated models with specialised Bio-CAD applications. If features beyond anatomy are required, geometry is usually translated into NURBS geometry for further ... -
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 ... -
Surface drag analysis after Ti-6Al-4V orthogonal cutting using grid distortion
(Elsevier Ltd, 2020)Surface integrity directly affects the mechanical behavior of the workpiece, which is especially relevant on fatigue behavior. To characterize the quality of the machined surface, aspects such as material damage, roughness ... -
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 ... -
