激光切割技术论文.docx

摘  要 激光切割是用激光精密切割金属、陶瓷、纸张的一种技术，可大大减少加工时间，降低加 工成本，提高工件质量。由于它具备精密制造、柔性切割、异型加工、一次成形、速度快、效 率高等优点，所以在工业生产中解决了许多常规方法无法解决的难题。 本文主要讲述了激光切割的原理、应用、发展历程以及国外发展现状。并阐述了国外先进 YAG 固体激光切割机、光纤激光切割机和 CO2 激光切割机的参数特性。深入了解了激光切割机。 通过对激光切割机的深入分析，掌握了现阶段激光切割机的前沿和发展水平，提高了学习 机械工程前沿的能力。 关键词：激光切割技术、应用、优缺点、发展现状 ABSTRACT Laser cutting is a technology that uses a laser to cut precise patterns in most all types of materials such as metal, ceramic, paper and so on. It can greatly reduce the processing time, reduce the processing cost and improve the quality.Because it has precision manufacturing, flexible cutting, the heterogeneous type processing, once shaping, speed and higher efficiency, so in industrial production in solving many conventional method can not solve the problem. This essay mainly talks about.the principles, applications, development process and the status of the overseas development of laser cutting,and also describes the advanced YAG solid-state laser cutting machine, laser cutting machine parameters and characteristics of the fiber CO2 laser cutting machine,to develop a greater understanding of the laser cutting machine. Through in-depth analysis of the laser cutting machine, we can master the level and the current development of cutting-edge laser cutting machine,and improve the learning ability of mechanical engineering frontier.
