一、概述随着航空航天、电子、仪表及医疗器械等工业的发展,许多高精尖产品的关键零部件(如飞机防冰系统、航空发动机气冷式叶片、陀螺仪表零件、计算机打印头等)都设计有许多微孔,以完成特定功能,从而提高产品的性能。例如,用打有5万个直径为0.064mm小孔的机翼装成的飞机在完成同样飞行任务的条件下,比无孔机翼的飞机可节省燃料40%。国外某型号飞柳的防冰系统要用激光加工出345000多个小孔。又如,用激光打信息孔制作光带,光带宽3mm,
I. Overview With the development of industries such as aerospace, electronics, instrumentation and medical devices, the key components of many sophisticated products (such as aircraft anti-icing systems, air-cooled aeroengine blades, gyroscope components, computer print heads, etc.) Many micropores are designed to accomplish specific functions to improve product performance. For example, airplanes fitted with 50,000 holes of 0.064mm in diameter can save 40% more fuel on non-porous aircraft compared to non-porous aircraft on the same mission. Foreign models of a certain type of anti-icing system to use the laser processing more than 345,000 holes. Another example is the use of laser information hole making light band, light bandwidth 3mm,
