Training and learning methods for engineering students, in the disciplines of product design manufacturing, are becoming more difficult complex since they have to integrate theoretical technical knowledge, skills computer-aided applications (CAx) collaborative work practices. Product Lifecycle Management (PLM) tools support structured practices CAx supports content creation. Both types software key Industry 4.0 development. They also evolve over time, incorporate new functionalities, change...

A 2D Finite Element Model set up using the Arbitrary Lagrangian Eulerian (A.L.E) formulation proposed in Abaqus/Explicit (v6.4) is employed to predict serrated chip formation during cutting process. No artificial criterion create or initiate formation. The sensitivity of prediction numerical and process parameters analyzed this paper. Experimental tests orthogonal conditions on machining AISI-4140 with coated uncoated cemented-carbide inserts were carried out validate results. They showed...

Abstract Background Despite computer‐aided design and manufacturing (CAD/CAM) technology improving prosthesis fit, errors inherent to digital workflow still exist. Purpose To measure scanning/milling errors, identify factors influencing marginal (MD) internal discrepancy (ID). Materials Methods After scanning, 22 conical abutments in 5 master casts, 6 suprastructures with more than 2 implants (3, 4, 6) were CAD designed. Angular deviation the vertical/horizontal planes analyzed using a...

Universities are one of the fundamental actors to guarantee dissemination knowledge and development competences related Industry Future (IoF) or 4.0. Computer Aided (CAX) Product Lifecycle Management (PLM) technologies key part in IoF. With this aim, it was launch a project focused on Manufacturing partially funded by La Fondation Dassault Systèmes. This communication presents review CAX-PLM training, four initiatives already place universities participating project, scope, approach...

Residual Stress (RS) pattern changes considerably depending on the width of plates and welding parameters, having effect fatigue strength. Most standards do not consider them in some works, yield stress is taken as residual value. It results a very conservative estimation life. Authors developed recently numerical model to predict more properly value RS plate thickness. In welded joint, considering alternating axial loads, evolution stresses multiaxial, becoming necessary its study....

Modelling of anatomical parts is usually tackled through triangulated models with specialised Bio-CAD applications. If features beyond anatomy are required, geometry translated into NURBS for further modification in parametric feature based design CAD systems. But, they remain quite unmanageable yet. The authors present, validate and implement a knowledge methodology that generates an anatomically personalised trachea stent point cloud data extracted from Computerised Axial Tomography...

Residual stress (RS) pattern of thick T-joint welds, which directly affects fatigue life, varies considerably depending on the thickness and number passes. Nowadays, most approaches to predict life do not consider RS real value due difficulty estimating them, hence, they tend be conservatives. However, recent works have demonstrated that considering conservative error in prediction can reduced down around 15%. In present work, performance multipass T-joints S275JR plates for a range from 20...

Abstract The use of surrogate models to determine scaling rules for product families has been proven be a powerful tool dimensioning complex shape geometries by replacing costly evaluate problems with almost instantly solve mathematical functions. However, there is broad range in the literature and each model can configured multiple ways. In addition, optimal selection its configuration highly conditioned case study nature. Consequently, nowadays it mandatory different configurations choose...

Tensile residual stress (RS) peaks near the weld toe accelerate crack generation and propagation stages reducing dramatically life of welded components. In order to relief RS, components are typically heat-treated. However, heat treatments can affect microstructure compromising mechanical properties. addition, their application in big structures is complex due size limitations. As an alternative, such as shot peening be locally applied. Moreover, they generate local compressive stresses...

Valves are mechanical devices for controlling fluid-flow in pipes of different diameter and service pressures used several industry sectors. Most demanding sectors add custom design requirements require product validation reports many times even before placing valve purchase orders varying quantities. Therefore, customer developer must be made compatible, reliably completed a report created, all as soon possible. In order to respond these market constraints, complete process from planning...
