Abstract
An efficient orthogonal velocity polishing tool (OVPT) was developed. The OVPT was installed on the end flange of an industry robot. The movement range of the industry robot reaches φ 1000 millimeter. The robot OVPT is a highly efficiency processing method for aspheric precision optics manufacturing. In this paper, a 360 mm diameter fused silica parabolic mirror was polished by the robot OVPT. The convergence of OVPT based on an industry robot is outstanding. After 4 times of polishing, a final surface error RMS 16.6nm was achieved, and the initial surface error RMS was 69.5nm. A polished surface roughness Ra 1.5nm was achieved by robot OVPT.
