This application relates to a multimodal adaptive aspherical lens polishing surface control method, aiming to solve the problems of over-polishing and under-polishing caused by the inability of existing technologies to adapt stiffness and vibration parameters according to the curvature zones of the lens. First, the surface curvature distribution data of the lens to be polished is obtained to identify the locations of high and low curvature regions. A polishing disk rotating around an axis is provided, with Ni-Ti based shape memory alloy wires embedded in an array within its elastic matrix, and several piezoelectric ceramic ultrasonic vibrators are embedded within it. Differential currents are applied to the alloy wires in different regions according to the curvature data, and the stiffness of the corresponding regions of the polishing disk is adjusted through a martensitic-austenitic phase transformation, with low stiffness adapted to high curvature regions and high stiffness adapted to low curvature regions. During polishing, the ultrasonic vibrators are synchronously controlled to output vibration parameters matching the curvature regions, achieving multimodal coupled polishing. This method effectively avoids over-polishing and under-polishing defects, balancing processing accuracy and efficiency, and meeting the requirements of high-end fields for nanometer-level surface accuracy of aspherical lenses.
