Laser cutting machine acousto-optic modulator scanning way: fast scanning micro machining system, laser cutting machine driven by center frequency of 102 MHZ pair Te02 acoustooptical deflector in the X-ray Y plane deflection, the beam through a flat field lens focus for the diameter of about 1. 0) Um micro speckle, laser cutting machine was carried out on the workpiece in raster scanning, every lum, draw a grid line scanning field is divided into 256 x 256 scanning points, scanning speed of 2. 5 x 106 HP/SEC, with another piece of acousto-optic crystal and photoelectric diode in real time by a closed-loop feedback compensation deflector in the entire field of scanning transmission inhomogeneity. To processing the bigger size, then by X-ray Y the motion of nc machine to realize scanning field splices. Laser cutting machine micro machining system with he-ne laser beam, using spot small principle to keep the laser focus dynamically on the scan. The 3 d CAD/CAM software combined with numerical control light laser scanning tools, and follow the newly developed laser curing polymer solution macro components rapid prototyping technology.
