Laser machining technology has many advantages, such as high efficiency, good quality, widely machining area, precise machining, and highly automation. It has a potential for solving difficult problems in traditional machining process, even to change the process procedure of traditional machining. The demand for machining thin metal sheet is growing and the machining technology is getting more important for many industrial applications. In the premises of raising the manufacturing capacity to maximum and optimizing product quality, the machining and application of thin metal sheet has become a popular researching topic. This paper introduces the remote laser cutting technology, including the remote cutting mechanism, theory analysis, process simulation, and descriptions of advantages and applications.
