Laser processing is the most common application of laser systems. According to the mechanism of interaction between the laser beam and the material, laser processing can be roughly divided into laser thermal processing and photochemical reaction process. Laser thermal processing is the use of a laser beam onto the surface of the material to produce thermal effects to complete the process, including laser cutting, laser marking, laser drilling, laser welding, surface modification and micromachining.
With the four major characteristics of high brightness, high directivity, high monochromaticity and high coherence, laser has brought some characteristics that other processing methods are not available. Since the laser processing is non-contact, no direct impact on the workpiece, no mechanical deformation. Laser processing no “tool” wear and tear, no “cutting force” acting on the workpiece. In the laser processing, the laser beam of high energy density, processing speed, processing is local, non-laser irradiated sites with no or minimal impact.The laser beam is easy to guide, focus and direction to achieve transformation, easily and with CNC systems for machining complex workpieces. Therefore, the laser is an extremely flexible processing method.
As an advanced technology, laser processing has been widely used in the manufacture of textiles and garments, footwear, leather goods, electronics, paper products, electrical appliances, plastics, aerospace, metal, packaging, machinery manufacturing. Laser processing has played an increasingly important role to improve product quality, labor productivity, automation, non-polluting and reduce material consumption.
