Abstract

The invention provides a correction method and device for the surface shape of a polishing disk in full-caliber polishing. The correction method for the surface shape of the polishing disk in full-caliber polishing comprises the following steps that (1) errors of the surface shape of the polishing disk are detected, and fixed point removal functions of the correction device are determined; (2) a correction path covering the whole surface of the polishing disk is set; (3) residence time is calculated; (4) the correction path obtained in the step (2) and the residence time, obtained in the step (3), of all points on the path are input into a numerical-control machining system, and correction machining is performed on the surface of the polishing disk. The errors of the surface shape of the polishing disk are eliminated by controlling the residence time, on all the points of the surface of the polishing disk, of the correction device; compared with a traditional disk surface shape correction method of adopting a large-size correction plate, the correction method has the advantages of being good in correction control determinancy and high in correction accuracy.

Description

technical field [0001] The invention belongs to the field of optical processing, in particular to a small tool correction method for the surface shape of a polishing disk in full-diameter polishing. Background technique [0002] The polishing of large-aperture planar optical components is traditionally mainly performed by the ring polishing process. The good fluidity of the asphalt disk in the ring polishing process enables it to fit well with the surface of the workpiece. However, the wear and tear on the asphalt disk caused by the workpiece during the processing The extrusion effect causes the shape of the disk surface to change and the flatness to decrease, which is not conducive to the control of the workpiece surface shape. At present, large-sized correction plates are mainly used in ring throwing to improve the flatness of the asphalt disc and obtain an ideal disc shape. The correction plate is generally made of materials such as microcrystals and ceramics with high h...
