为提高超精密曲面结构化的可行性和效率，开发了一种闭环快速刀具伺服（FTS）曲面图形化与测量系统，该系统包括基于特征的刀具轨迹生成、嵌入式曲面测量和集成曲面特征工具包等功能模块。开发了一种专用于FTS表面图形化和在机表面测量（OMSM）过程控制的控制器HUCNC。算法被开发用于数据格式化和将设计的图案转换成FTS切割点（最多500万个点）。所提出的闭环FTS加工系统的可行性和性能被证明成功地产生典型的功能结构化表面，包括周期性结构，图案和镶嵌，生物表面，轮廓和字符组合。结果表明，基于特征的FTS图案化和表面表征系统为高精度功能结构表面的设计和制造提供了一个有前途的解决方案。集成的OMSM系统和表面表征工具包可对加工的功能表面进行快速检测和质量控制。
To improve the feasibility and efficiency of ultra-precision surface structuring, a closed-loop fast-tool-servo (FTS) surface patterning and measurement system is developed with functional modules of feature-based tool path generation, embedded surface measurement and integrated surface characterisation toolkit. A dedicate controller HUDCNC is developed for the process control of FTS surface patterning and on-machine surface measurement (OMSM). Algorithms are developed for data formatting and transformation of designed patterns into the FTS cutting points (maximum number of 5 million points). The feasibility and performance of the proposed closed-loop FTS machining system are demonstrated by successfully generating typical functional structured surfaces including periodic structures, patterns and tessellations, biological surfaces, profile and character combinations. The results indicate that the feature-based FTS patterning and surface characterisation system provides a promising solution to the design and manufacturing of high-precision functional structured surfaces. The integrated OMSM system and the surface characterisation toolkit allow the fast inspection and quality control of the machined functional surfaces.
