Abstract

The invention relates to an FFS radome machining method and machining device based on a multi-degree-of-freedom laser robot. Firstly, model design of an FFS radome is conducted through three-dimensional modeling technology, a to-be-machined conformal metal radome body is obtained through a spinning forming process, and then machining of all FFS unit structures is achieved through track control of the laser robot combined with a double-degree-of-freedom mobile platform. Laser non-contact focusing is achieved through a CCD image sensor. The FFS radome machining method and machining device have the beneficial effects that a laser non-contact machining mode is adopted, the machining process does not produce a stress effect on the radome body, the universality is high, machining of all the FFS unit structures can be completed in a machining cycle, and the work efficiency is high.

Description

technical field [0001] The invention relates to the field of robot laser processing technology and microwave band radome technology, in particular to a FSS radome processing method and processing device based on a multi-degree-of-freedom laser robot. Background technique [0002] Frequency Selective Surface (FSS) refers to periodically arranged metal resonant patches or metal surface resonant slot structures. It is essentially a spatial filter, and its structure can achieve excellent frequency selection characteristics. According to its structure Different can realize band-pass, band-stop, high-pass, low-pass and other characteristics of electromagnetic waves. The principle is that when an electromagnetic wave of a certain frequency is incident on the FSS, if it resonates with the FSS, the incident electromagnetic wave will be fully reflected (the patch type is band-stop) or fully transmitted (the slot structure is band-pass). [0003] With the development of modern high te...
