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 ...

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. ...

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. ...
