      "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 ...

      Abstract : "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. ...
