Compared with the development speed of other cutting technologies, three-dimensional laser cutting technology has been widely used in metal and non-metal materials, and is a "rising star" in the field of machining. The application of 3D laser cutting machine brings good news to many large 3D workpieces, which not only improves the work efficiency, but also improves the production quality of products. As the saying goes, "cutting iron like mud", "a good helper in workshop production" and other words summarize the advantages of three-dimensional laser cutting machine with flexible processing, fast cutting speed and high work efficiency. Therefore, the development of three-dimensional laser cutting machine meets the needs of the market and is a powerful tool for modern machining.

With the development of science and technology, in the manufacturing and processing industry, robots are introduced to expand the processing range of laser cutting machines, improve the stability of machine operation and reduce environmental pollution. Three dimensional laser cutting machine has entered the processing market for many years, and has been active in all walks of life with its unique advantages.

In addition to the addition of three-dimensional manipulator, the use of laser is also its highlight. Through the line of sight of the laser, we can obtain a lot of information, expand the detection range and improve the accuracy, and cooperate with the manipulator to recognize the machined parts. In the process of working, the laser can accurately and quickly obtain the position of the workpiece and the effect of cutting, then convert the posture of the manipulator through the spatial coordinate system, and then give the suitable path of the manipulator according to the distance between the manipulator and the workpiece, and complete a series of cutting work under the guidance of the laser. Based on the system sensing function of laser, it can set the cutting path in advance according to the shape and characteristics of the workpiece, and maintain a certain distance from the workpiece in the process of processing, which provides the necessary conditions for realizing the flexible processing of products. In addition, the laser and manipulator can be adjusted and re positioned at any time in the processing process, which not only improves the processing accuracy and precision of products, but also ensures the quality of products. At the same time, it also well explains the flexible processing advantages of three-dimensional laser cutting machine.

The laser in three-dimensional laser cutting machine is a new technology for the manufacturing industry, but the manipulator is mainly used to accurately locate the machined parts. The application system of laser guides the manipulator to simulate the shape and contour of the workpiece, and then controls the motion trajectory of the manipulator through the teaching pendant to complete the section to be cut. The two rely on and cooperate with each other in the process of processing, and combine their own advantages into optimization, so as to bring greater benefits.
