一、概述在工业生产领域中,激光加工技术正在各工业先进国家飞速地发展着。在表面热处理,表面合金化、焊接以及切削等领域中正在愈来愈广泛地被利用。其所以能与传统加工技术相竞争,是有着其本身的许多特点。简要地说: (1)激光加工基本上是一个热加工过程,由于其工作部分是个功率密度极高的能源,故加工过程非常迅速,热量来不及传送太远,因此,热影响区小(约0.1～1mm),加工质量较好,热变形影响较小,而生产率
I. Overview In the field of industrial production, laser processing technology is rapidly developing in various industrialized countries. It is being used more and more widely in the fields of surface heat treatment, surface alloying, welding and cutting. So it can compete with the traditional processing technology, has its own many features. Briefly speaking: (1) Laser processing is basically a thermal processing process. Since its working part is an energy source with extremely high power density, the processing speed is very fast and the heat is too late to be transmitted. Therefore, the heat-affected zone is small (about 0.1 ~ 1mm), processing quality is better, thermal deformation less affected, and productivity
