Article scientifique
Abstract : "This paper deals with the numerical modelling of non-destructive testing of composite parts using active thermography. This method has emerged as a new approach for performing non-destructive testing (NDT) on continuous carbon fibre reinforced thermoplastic polymer (CCFRTP) components, particularly in view of detecting porosity or delamination. In this context, our numerical model has ...
Additively Manufactured Multifunctional Composite Parts with the Help of Coextrusion Continuous Carbon Fiber: Study of Feasibility to Print Self-Sensing without Doped Raw Material

Article scientifique
Abstract ; "Nowadays, the additive manufacturing of multifunctional materials is booming. The fused deposition modeling (FDM) process is widely used thanks to the ease with which multimaterial parts can be printed. The main limitation of this process is the mechanical properties of the parts obtained. New continuous-fiber FDM printers significantly improve mechanical properties. Another limitation ...

Abstract : "The number of FabLabs has been steadily increasing over the last few years. Their main objectives are to sensitize its public on Science, Technology, Engineering, and Math (STEM) education through the digital manufacturing chain of an object and to allow the large public to make their own objects. Through, the increasing popularization of these advanced technologies, it becomes more ...

" This article aims to make a review of the existing benchmark artifacts and to summarize the main requirements chosen by authors. From this state of the art, a new benchmark artifact is proposed by adapting an existing one to fulfil its missing characteristics. Measurements possibilities in terms of dimensions are enumerated and organized using ISO 286 dimensional intervals as presented in the ...
Green Ceramic Machining: Influence of the Cutting Speed and the Binder Percentage on the Y-TZP Behavior

- Article scientifique
Article scientifique
Abstract : "The demand for inert bioceramics is always increasing in the dental field. Yttrium oxide tetragonal zirconia polycrystals (Y-TZP) are oxide ceramics which are currently used because of their interesting mechanical properties due to a toughening transformation. Industrially speaking, machining of the ceramic before sintering (green body) is very common because it allows a better productivity ...
Green Ceramic Machining: Determination of the Recommended Feed Rate for Y-TZP Milling

- Article scientifique
Article scientifique
Abstract : "Manufacturing of advanced ceramic parts exhibiting complex geometries is laborious and expensive. Traditionally, the machining is carried out on a so-called ‘green ceramic’: a compact composed of ceramic powder held with the help of a binder. This difficulty is due not only to the composition of the material, but also to the lack of methods that determine optimal machining parameters. ...

Contribution to ESAFORM2021.
Abstract :
"When modelling a cutting operation, the constitutive model of the machined material is one of the key parameters to obtain accurate and realistic results. Up to now, the Johnson-Cook model is still the most used, even if an increasing number of models, such as the Hyperbolic TANgent (TANH) model, were introduced last years to overcome its limitations and ...

Contribution to euspen’s 20th International Conference & Exhibition (Geneva, CH, June 2020)
Abstract :
"The ceramic microcomponents have very interesting mechanical and thermal properties in an extreme environment such as a high temperature, a corrosive environment, etc. Unfortunately, the principal limitation of ceramic material usage is its shaping because of the brittlness of the material. ...

Contribution to "euspen’s 19th International Conference & Exhibition, Bilbao, ES, June 2019"
Abstract :
"The requirements for quality amelioration of engineered products are increasingly stringent, and specially when the miniaturization and difficult-to-machine materials are considered. The development of hybrid machining processes (HMPs) answers this problem.
Indeed, HMPs are variants of ...

Contribution to "Euspen’s 17th International Conference & Exhibition, Hannover, DE, May 2017".
Abstract : "The demand for micro products has increased gradually since last decades in various areas, requiring the development of micro manufacturing processes. Micro manufacturing is characterized by the size of functional features (smaller than 10 um), a high precision, a good surface finishing and ...
