Introduction and application of 3D fiber laser cutting robot
**1. Overview**
The 3D fiber laser cutting machine is a highly advanced system that combines a specialized fiber laser cutting head, a high-precision capacitive tracking system, a powerful fiber laser, and an industrial robot. This equipment enables multi-angle and multi-directional cutting of metal sheets with varying thicknesses, making it ideal for complex 3D workpieces. It is widely used in industries such as metal processing, machinery manufacturing, and automotive parts production.
**2. Three-Dimensional Fiber Laser Cutting Robot**
**(1) Principle of 3D Laser Cutting**
After the laser is generated, it is directed through mirrors and focused onto the material via a collecting lens. The intense heat from the laser causes the surface to rapidly heat up, leading to melting or vaporization. As the laser head moves along the desired path, the material is cut precisely, achieving the intended result.
**(2) Selection of Fiber Lasers**
The power of the fiber laser is chosen based on the thickness of the metal being cut. Common power levels include 200W, 300W, 400W, 500W, and 1000W. Each laser is paired with an appropriate cooling system to ensure stable operation. Additionally, the length of the fiber cable is selected based on the robot’s reach and the size of the workpiece to meet specific cutting requirements.
**(3) Requirements for Auxiliary Gas**
For optimal performance, 99.99% pure oxygen is typically used as the auxiliary gas. It enhances cutting accuracy, speed, and the quality of the cut surface.

**3. Features of 3D Fiber Laser Cutting Robots**
**(1) High Flexibility**
This system is especially suitable for small-batch, complex 3D sheet metal cutting. Its flexibility is evident in two key areas: first, it can process almost any type of metal plate using a CNC program. Second, the cutting path can be easily adjusted by modifying the program, which is particularly useful when dealing with different part designs. Unlike traditional dies, which are costly and inflexible, 3D laser cutting offers a more efficient and cost-effective alternative.
In practice, this technology improves product quality, increases efficiency, reduces development time, lowers labor costs, and minimizes material waste. Despite the initial investment, many automotive and aerospace companies in China have adopted 3D laser cutting systems, and research institutions are also investing in this technology.
**(2) Advantages and Disadvantages of Fiber Laser Cutting Robots**
Industrial robots replace five-axis machines for spatial cutting, offering similar capabilities at a lower cost. While their repeatability is slightly less (±100μm), it still meets the precision needs of automotive sheet metal and chassis applications.
Fiber lasers provide better cutting quality, lower system costs, longer lifespan, and reduced maintenance compared to traditional lasers. Their ability to transmit through optical fibers makes them ideal for integration with robotic systems. However, they are limited to metal materials due to the 1064nm wavelength, which is not efficiently absorbed by non-metals.
The combination of robots and fiber lasers allows for simultaneous cutting, trimming, and punching, reducing post-processing and lowering labor and mold costs. Offline programming software simplifies the process, making it ideal for small-batch and customized production.
Advanced control systems, imported laser heads, and intelligent manipulators ensure high-speed, high-precision, and reliable cutting. These features make 3D fiber laser cutting one of the most promising technologies in modern manufacturing.

**6. Conclusion**
The future of 3D laser processing lies in higher precision, speed, flexibility, and intelligence. While China has made progress, there are still gaps in high-power laser development and theoretical research. Compared to foreign technologies, domestic systems lack advanced beam quality and deep understanding of the laser-material-gas interaction. Further research and development are needed to fully harness the potential of 3D laser cutting.
