高陡度保形整流罩的机器人高精度轮带抛光加工技术
Precision Robotic Belt Grinding Technology for High-Steepness Conformal Radome
【摘要】 高陡度保形整流罩由于其非常规的外形结构,传统抛光技术无法对其进行高效确定性抛光,亟需开发一种针对高陡度保形整流罩的适应性好、自由度高、加工稳定性好的抛光装置及工艺方法。本文首先构建了适用于高陡度保形整流罩的机器人轮带抛光装置,其次基于抛光工艺试验建立了公自转轮带抛光去除函数模型,最后开发了等重叠率抛光轨迹和驻留时间求解算法,实现了高陡度保形整流罩的修形抛光,将表面粗糙度R_a值降低至3 nm以内,整体面形误差PV值收敛至3μm以内。
【Abstract】 High-steepness conformal radome, due to its unconventional shape, cannot be effectively deterministically polished using conventional techniques. Therefore, it is imperative to develop a polishing apparatus and process method featuring good adaptability, high degrees of freedom, and excellent machining stability specifically for high-steepness conformal radome. This study first constructed a robotic belt grinding system suitable for high-steepness conformal radome. Secondly, based on polishing process experiments, a removal function model of revolution-and-rotation belt grinding was established. Finally, constant-overlap grinding path and a dwell time solution algorithm were developed, enabling form correction polishing of high-steepness conformal radome, reducing the surface roughness Ra value to within 3 nm and converging the overall surface form error PV value to within 3 μm.
