Embodiment
[0053] In this embodiment, the magnetorheological numerical control polishing machine is used as the processing equipment, and the circular flat mirror with a diameter of 100 mm is used as the component to be processed, and combined with Figure 2 to Figure 7 , to illustrate the specific embodiments of the present invention. In the following description, the method for smoothing the residence time during the processing of the optical element according to the present invention is referred to as the smoothing method for short. Under normal circumstances, the removal function of the magnetorheological polishing machine is non-circularly symmetrical, figure 2 (a) is the removal function distribution I(x, y) when the magneto-rheological polishing head stays at the coordinate point x=0, y=0 for 3 seconds. This embodiment takes figure 2 The shape distribution of the removal function distribution shown in (a) about x=0, y=0 coordinate point rotated 180 degrees is used as the time ...
