| description | In order to understand the work hardening phenomenon and mechanism of laser-assisted machining (LAM) of Si<sub>3</sub>N<sub>4</sub> ceramics, the work hardening degree of LAM Si<sub>3</sub>N<sub>4</sub> under different material removal modes was studied. Two sets of single-factor experiments were performed in which the laser power and the cutting depth were changed respectively. The results show that work hardening is the result of the combination of heat and cutting deformation during cutting. The work hardening degree decreases with the increase of material softening degree. When the material is removed plastically, the work hardening degree is 110−115%. |
