; Rivière-Lorphèvre, Edouard; Ducobu, François; Dolimont, Adrien; Petit, Fabrice; Juste, Enrique, HE Condorcet
Acte de conférence ou de colloqueContribution 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 ... -
Development of the hybrid sequential machining: laser machining and milling
2016, DEMARBAIX, Anthonin; Rivière-Lorphèvre, Edouard; Ducobu, François; Filippi, Enrico; Petit, Fabrice; Preux, Nicolas, HE Condorcet
Acte de conférence ou de colloque"The aims of this paper is to study the advantages and disadvantages of laser micro-machining and the micro-milling. The final goal is to couple these processes in the same structure. The sequential hybrid process is subtractive-subtractive it combines the laser u-machining and the u-milling. The samples are machined with the two processes to compare the dimensional tolerance and the geometrical ... -
Experimental investigation on green ceramic machining with nanosecond laser source
03 décembre 2020, DEMARBAIX, Anthonin; Ducobu, François; Juste, Enrique; Petit, Fabrice; Duterte, Charles; Rivière-Lorphèvre, Edouard, HE Condorcet
Article scientifiqueAbstract : "Yttrium oxide tetragonal zirconia polycrystals (Y-TZP) is an inert bioceramic used for many bio-implantable applications that request a high accuracy which is difficult to achieve with the current technologies. Laser machining of hard ceramic is difficult because the interaction of the laser beam with the material can lead to microcracks and surface modifications of the microstructure. ... -
The Hybrid Machining of Ceramic: The choice of production stage
30 mai 2017, DEMARBAIX, Anthonin; Rivière-Lorphèvre, Edouard; Ducobu, François; Filippi, Enrico; Preux, Nicolas, HE Condorcet
Acte de conférence ou de colloqueContribution 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 ...
