能切割、钻孔和焊接的数控激光系统巳由美国Raytheon激光中心研制成功。PW-561型固态激光系统能加工长18英寸、重100磅的金属体。用激光加工金属比之其他加工方法有许多优点,诸如精度高、无热损伤、工具无磨损、夹具成本低,加工时不接触到工件以及速度快、操作可靠等。该系统包括快速编程简化数控软件(计算机数控器系统运动精度可达0.0001英寸)和通过激光器聚光镜而显示的闭路电视等。PW-561型激光器能点焊或缝焊各种不同的金属和较难焊接的金属,如铜、铝、钨和钼等,焊透率可达0.08英寸。也能钻直径为0.002～0.02英寸,深为0.5英寸的孔。采用旋转
CNC laser systems that can be cut, drilled and welded have been successfully developed by the Raytheon Laser Center in the United States. PW-561 solid-state laser system can process 18 inches long, weighing 100 pounds of metal body. There are many advantages to using laser to machine metal over other processing methods such as high precision, no thermal damage, no tool wear, low fixture cost, no workpiece contact during machining, fast speed, and reliable handling. The system includes quick programming and simplified numerical control software (computer numerical control system motion accuracy of up to 0.0001 inches) and through the laser condenser display closed-circuit television. PW-561 lasers can spot weld or seam weld a wide range of metals and difficult-to-weld metals such as copper, aluminum, tungsten and molybdenum with penetration rates up to 0.08 inches. It is also possible to drill holes with a diameter of 0.002 to 0.02 inches and a depth of 0.5 inches. With rotation
