And equipment.
Technical background
In the three-dimensional complex component Precision Machining of aerospace, there are a large amount of irregular surface component surface pattern systems
Work, size is repaired and milling quarter type demand, and common feature is surface fine processing, and scantling is generally several meters, manufacture essence
Degree reaches some tens of pm, and material is different, belongs to " complex-curved across the scale " manufacture of typical different materials.Traditional multiaxis machine
Tool processing method machining accuracy and consistency difference and production efficiency it is extremely low, it is difficult to meet application request.
For example, it is anti-to consolidate surface antenna in guided missile and radome of fighter frequency selection table (FSS) antenna radar cover and spacecraft
In terms of emitter, size is manufactured generally from 0.3~3m etc., but working image size required precision reaches 10~20 μm of magnitude.
There are two types of the conventional molding process of existing frequently-used FSS antenna house, and one is indirect branch methods, on a thin film substrate using plating
Film is lithographically derived flexible FSS film, is then transferred on antenna house.But when FSS film piecemeal is covered in antenna house surface, splicing is missed
Difference etc. causes FSS periodic microstructures integrality and accuracy to be destroyed, and directly affects antenna house wave transparent performance and Stealth Fighter,
It causes larger with designing technique index difference, is unable to satisfy model technical requirement.Another kind is digitlization machining, should
Method difficult point is the design of system of processing and the control of machining accuracy and mechanical stress, in processing the accumulation of various errors and
Deformation can seriously affect the transmission characteristic of FSS antenna house.
The hollow blade ceramics core finishing technology of aircraft engine is always one of the key technology in hollow blade casting, it
Determine service performance and the service life of the vane size precision, qualification rate and casting cost and aircraft engine.With starting
The development of machine technology, the air cooling structure of blade tend to complicate, as formed hollow blade air cooling structure ceramic core also by

1.0mm) cause size core finishing difficulty larger, existing artificial mechanism core finishing means not can guarantee precision, lead to low precision and efficiency
It is low, it is difficult to meet quality requirement.
The type lightweight of milling quarter is the difficulties of aerospace and weaponry manufacture, is to improve rocket, guided missile to have an high regard for
Than and comprehensive performance important channel.However, the country generallys use traditional artificial quarter type technique now.Due to artificial quarter type mistake
Error accumulation is larger in journey, cannot automate, and processing efficiency is low, and the process-cycle is long, not can guarantee part size accuracy and
Consistency it is difficult to ensure that glue film carves disconnected, required precision needed for not injuring parent metal and trim line, while also needing a large amount of
Quarter pattern plate.
Laser is due to focal beam spot diameter is small, energy density is high, noncontact procession (no tool wear), flexible journey
The features such as degree is high, without exposure mask, is very suitable to difficult-to-machine material: ultra-soft, superhard, super special material and the various complexity such as crisp, ultra-thin
Shape microfabrication.But the optical characteristics and physico-chemical properties due to above-mentioned rapidoprint have biggish difference, it is right
Optical maser wavelength, waveform and power have different requirements.The prior art can only use single laser source, it is difficult to reach to above-mentioned all
Material can carry out precision machined purpose.If using a three-dimensional laser processing equipment for above-mentioned a certain Precision Machining
Using then must being just able to satisfy three of the above application using the three-dimensional laser processing equipment of more different optical maser wavelength light sources and want
