      "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 ...

    • 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 ...

    • A new manufacturing chain for ceramic shaping: sequential combination of milling and laser machining in green ceramicPeer reviewedOpen access

      Acte de conférence ou de colloque
      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. ...

    • Prediction of local sintering in laser beam machining of green Y-TZP ceramicPeer reviewedOpen access 

      20 mai 2020, Ducobu, François; Rivière-Lorphèvre, Edouard; DEMARBAIX, Anthoninorcid-id; Lauwers, Berth, HE Condorcet
      Article scientifique
      Abstract : "Laser beam machining of Y-TZP engineering ceramic material is carried out in green stage to increase the material removal rate. The generation of hot spots may cause local sintering of the ceramic material leading to a decrease of the mechanical properties of the final sintered component. This paper presents the implementation of alternative laser beam paths to reduce the hot spots ...
