Abstract

The application discloses a path generation method for treating an aspheric surface in a gasbag polishing way. The path generation method comprises the following steps: establishing a contact model ofa polishing tool and an aspheric surface workpiece; generating a spiral curve formed by sequentially connecting a plurality of polishing paths according to a searching point by point algorithm; and adjusting the distance on the polishing path in the radial direction through the contact model. Based on the polishing path generated according to Archimedes screw, physical and uniform covering of thesurface of the workpiece is realized on the aspheric surface.

Description

technical field [0001] The present application relates to the technical field of mechanical processing, in particular to a path generation method for polishing an aspheric surface by using an airbag. Background technique [0002] In traditional polishing methods, polishing tools are usually rigid. Rigid polishing tools can cause scratches and subsurface damage to the surface, degrading the quality of the polished surface. Compared with traditional rigid polishing tools, bladder polishing tools are flexible, which can leave fewer scratches on the surface and reduce subsurface damage. Due to the flexibility of the polishing tool, the airbag polishing method has advantages in processing curved surfaces such as aspheric surfaces. [0003] The planning of the polishing path is an important part of the polishing process. Whether the polishing path can achieve a physically uniform coverage of the workpiece surface affects the final quality of the workpiece surface. In fact, ther...
