What is a Laser Cutting Robot?

The 3D fiber laser cutting robot system uses advanced components like a fiber optic laser cutting head, precise capacitive tracking system, and an industrial robot arm to flexibly cut metal sheets & pipe of varying thicknesses from different angles and directions.

With the robotic flexibility, it can be programmed for various workpiece sizes, shapes, and paths. By using fiber optics to transmit the laser to the cutting head and then focusing it with a focusing system, it is possible to cut and engrave a variety of three-dimensional metal plates in different directions.

Compared to 2D laser cutting, the 3D laser cutting system continually adjusts the head’s direction to ensure it remains perpendicular to the workpiece surface, ensuring superior cutting quality.

Advantages of Robot in 3D Laser Cutting

Traditional mechanical parts have been replaced by complex 3D profiles such as bending, hydroforming, deep drawing, molding, die-casting tubes or pre-welded assemblies. Laser cutting robot arm have become an effective tool for solving problems of geometric complexity of parts. Their 6-axis nature allows the 3D laser cutting head to freely reach any point of the part, making them ideal for handling complex part geometries.

Robotic laser cutting systems are efficient, flexible automation solutions that allow operators to easily plan and set up cutting tasks through advanced programming interfaces and intelligent algorithms. Compared to multiple conventional laser cutting machines, a single robotic cutting system can achieve equal or better production performance.

In automotive sheet metal component manufacturing, robotic laser cutting offers significant advantages over traditional methods. For three-dimensional cutting of complex structures, robotic laser cutting can solve the problem of open die stamping, plasma cutting or five-axis machine tools. Especially in the trimming and punching process, robotic laser cutting reduces the difficulty of making molds and improves production efficiency. Compared with traditional methods, robotic laser cutting avoids the problem of cracking on the edge caused by multiple stack welding, reduces the scrap rate, and reduces the production cycle and cost.

To meet the demand for automotive sheet metal coverings and chassis parts, a combination of industrial robots and fiber lasers is used for 3D cutting. Although the positioning accuracy of the industrial robot is slightly lower, it is sufficient to meet the automotive industry’s requirements for accuracy. This solution lowers system costs, reduces energy consumption and maintenance, and shrinks the system footprint.
