A kind of experimental method for quickly forming the Gaussian-shaped removal function is proposed. The corresponding nozzle height range of Gaussian-shaped removal function is obtained by the investigation of the relationship between the material removal appearance and the intersection point of the fluid jet center and the workpiece under the tilt fixed-point incidence mode. As for the definite process parameters, the corresponding nozzle height of Gaussian-shaped removal function is obtained by the addition of the rotary motion of the principal axis. The symmetry of the Gaussian-shaped polishing spot is analyzed and the dynamic removal experiment is conducted. The results show that the dynamic removal process based on Gaussian spots possesses a good stability, which can meet the demand of the ultra-precision optical manufacture and also can confirm the efficiency and reliability of this method.
