      Article scientifique
      "In this paper,the NF E 66-520-5 standard, dedicated to the determination ofthe optimal cutting parameters suitable for ductile material, is applied to the pre-sintered ceramic Y-TZP. The objective of the standard is to calculate the specific cutting energy of the forces created between the chosen tool and material during machining operation. Specific cutting energy is the energy required to remove ...

    • Binder influence on green ceramic machining by means of milling and laser machiningPeer reviewedOpen access

      "The micro manufacturing of ceramic components is technologically challenging especially when complex shapes and micro features are required. A hybrid manufacturing chain is developed for non-sintered(green) blanks machined using sequentially a cutting tool and a laser source. During the preparation of the green blank, a binder is added to the powder to improve compaction. The amount of binder can ...

    • Development of the hybrid sequential machining: laser machining and millingPeer reviewedClosed access 

      2016, DEMARBAIX, Anthoninorcid-id; 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 ...

    • Green Ceramic Machining: Influence of the Cutting Speed and the Binder Percentage on the Y-TZP BehaviorPeer reviewedOpen access 

      21 mai 2020, DEMARBAIX, Anthoninorcid-id; Ducobu, François; Preux, Nicolas; Petit, Fabrice; Rivière-Lorphèvre, Edouard, HE Condorcet
      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 ...

    • The Hybrid Machining of Ceramic: The choice of production stagePeer reviewedClosed access 

      30 mai 2017, DEMARBAIX, Anthoninorcid-id; Rivière-Lorphèvre, Edouard; Ducobu, François; Filippi, Enrico; Preux, Nicolas, HE Condorcet
      Acte de conférence ou de colloque
      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 ...

    • Impact of Green Ceramic Hybrid Machining (GCHM) on Reliability and Repeatability of the Properties of Sintered Yttrium-Tetragonal Zirconia Polycrystal PartsPeer reviewedOpen access 

      20 juin 2023, Ducobu, François; DEMARBAIX, Anthoninorcid-id; Rivière-Lorphèvre, Edouard; Spitaels, Laurent; Petit, Fabrice; Preux, Nicolas; Duterte, Charles; Mulliez, Marylou; Lauwers, Bert, HE Condorcet
      Article scientifique
      Abstract : "The innovative Green Ceramic Hybrid Machining (GCHM) process sequentially combines milling with a cutting tool (GCM, Green Ceramic Machining) and laser beam machining (GCLBM) of a ceramic material (black Y-TZP in this study) at the green stage mainly to increase productivity, avoid taper angle limitations of laser beam machining, and obtain micro-features. The study focuses on ...
