As an optical hard brittle material, glass-ceramic is widely used in radome, astronomical telescopes, and laser industries. However, an efficient method for machining optical free-form surface of glass-ceramic still needs to be studied by academia and industry. In this study, a laser-assisted fast tool servo machining device for glass-ceramic is developed. The theoretical stiffness of semicircular flexure hinge in the device is calculated by flexibility matrix method. The displacement output characteristics of the device are verified by simulation and displacement measurement experiment. Static and dynamic temperature measurement experiments of glass-ceramic are carried out respectively. The free-form surface morphology of glass-ceramic is obtained through machining experiment. Laser-assisted fast tool servo machining can reduce surface roughness by 24.4% and tool wear by 35.7% compared to conventional machining, which fully proves that the laser-assisted fast tool servo machining device can obtain higher machining quality of optical free-form surface.
