Material removal mechanism of laser-assisted grinding of RB-SiC ceramics and process optimization [PDF]

open access: yesJournal of the European Ceramic Society, 2019
Laser-assisted grinding (LAG) is a promising method for cost-effective machining of hard and brittle materials. Knowledge of material removal mechanism and attainable surface integrity are crucial to the development of this new technique. This paper focusing on the application of LAG to Reaction Bonded (RB)-SiC ceramics investigate the material removal
