Abstract

Polycrystalline ZnSe ceramics, an extreme difficult to machine material due to the inherent nature low hardness, low fracture toughness, and high brittleness, has been wildly used in the laser and infrared optics manufacturing field. However, the surface defects are inclined to nucleation and propagation through conventional single point diamond turning, the hybrid technology micro-laser-assisted machining (μ-LAM) has been proposed to combine the laser-assisted machining and ultra-precision single point diamond turning, which demonstrated the potential in improving the machining efficiency and surface integrity. In the study, comparative experiments have been conducted to verify the feasibility of μ-LAM on ZnSe ceramics. Furthermore, orthogonal experiments have been carried out to investigate the effect of machining parameters and laser parameters on surface quality and the optimum parameters subjected to the μ-LAM of ZnSe ceramics.
