Three-robot system for efficient large-aperture mirror lapping

Modern optical systems prioritize precision and resolution, increasing demand for large-aperture mirrors. To enhance manufacturing efficiency, we propose a multi-robot collaborative optical manufacturing technology utilizing the Preston equation. Our study correlates the rotational speed of lapping tools with material removal. For a 1450 mm diameter mirror, the process achieved a 61.96% reduction in total manufacturing time to 52 hours over eight cycles. The surface quality within the central 90% aperture was simultaneously improved, with the PV value decreasing from 80.14λ to 5.42λ (λ = 632.8 nm) and the RMS value decreasing from 8.19λ to 0.75λ.. These findings confirm that the three-robot system effectively shortens manufacturing time, providing insights for advancing intelligent optical manufacturing and enhancing production capabilities..
