Abstract

The invention discloses a precise polishing robot system for large-caliber complex optical lenses. The precise polishing robot system comprises an optical lens polishing robot module, a sensor module, a signal processing computer module and an active compliance control module. The polishing robot integrates a processing part, and the active compliance control module controls the rotation speed of a polishing disc and trajectories of the polishing robot. An error curved surface adaptive trajectory planning module of the signal processing computer module enables removed curved surfaces to be close to error curved surfaces as much as possible, and accordingly, the convergence rate is improved effectively. The precise polishing robot system has the advantages of high integration level and convergence speed.

Description

technical field [0001] The invention relates to a device in the field of ultra-precision machining, in particular to a precision grinding and polishing robot system suitable for hard, brittle and difficult-to-machine materials such as large-caliber complex optical mirrors. Background technique [0002] In recent years, large-aperture complex optical mirrors have been widely used in the fields of high-resolution earth observation satellite optical cameras, sky observation satellites, and deep space scientific exploration. However, due to the hard and brittle characteristics of the mirror material, its processing accuracy High, difficult, and long cycle seriously affect its application. In the optical mirror processing process, lapping (grinding, polishing) is an important process connecting grinding and subsequent magnetorheological processes, and its processing efficiency and quality greatly affect the quality and efficiency of mirror processing. [0003] Different from the...
