    Area of Science:

    • Optics fabrication
    • Precision engineering
    • Manufacturing technology

    Background:

    • Deterministic optics fabrication relies on precise tool paths for surface quality.
    • Conventional spiral and raster paths can introduce waviness and struggle with varied surface shapes and errors.
    • Existing methods lack adaptability and efficiency in tool-path planning.

    Purpose of the Study:

    • To introduce an innovative zonal Random Adaptive Path (RAP) for deterministic optics fabrication.
    • To address limitations of conventional tool paths regarding adaptability, efficiency, and accuracy.
    • To improve the manufacturing of precision optical surfaces.

    Main Methods:

    • Developed a zonal Random Adaptive Path (RAP) incorporating part boundary for shape adaptability.
    • Implemented an average threshold strategy for efficient and selective error correction.
    • Utilized multi-pass processing with RAP to achieve desired surface residuals.

    Main Results:

    • RAP demonstrated superior performance compared to conventional tool paths.
    • The proposed method achieved the best surface quality.
    • RAP significantly reduced overall processing time.

    Conclusions:

    • The zonal Random Adaptive Path (RAP) is an effective solution for deterministic optics fabrication.
    • RAP offers enhanced adaptability to different surface shapes and localized errors.
    • This approach leads to improved efficiency and superior surface quality in optics manufacturing.
