The core value of 3D robotic cutting lies in its ability to handle complex curved surfaces, three-dimensional structures, and flexible production requirements. Although its absolute accuracy is slightly lower than that of traditional five-axis laser cutter, its advantages—such as lower cost, larger workspace, and flexible programming—make it an indispensable solution in fields like automotive, aerospace, and custom manufacturing. Especially for irregular and non-standard parts ,its high flexibility and strong adaptability are its big advantages; Through multi-axis coordination, it can freely process complex curved surfaces, eliminating the need for specialized tooling. Offline programming enables rapid response to small-batch custom demands, significantly reducing production preparation time.
Robot accuracy has a significant impact on laser cutting, directly affecting processing quality, efficiency, and applicable range. Specific problems caused by insufficient accuracy:
1. Geometric image distortion
The smaller the circle, the higher the precision required of the robot.
The Fanuc 20iB robot is used to cut circles of different diameters.
2. The quality of the incision has deteriorated.
Increased surface roughness: Insufficient precision can cause the laser focus position to shift, leading to uneven energy distribution and resulting in burrs and slag on the cut surface.
3. Process limitations
Achieving high-precision machining of features such as micro-holes and narrow slits is difficult and usually requires a higher-precision gantry-type laser cutting machine.
Conclusion:
We chose high-precision FANUC brand robots. The FANUC 20iB robot is a mature and reliable 3D cutting solution, especially suitable for industries requiring long-term continuous operation and medium precision (such as automotive parts and metal products).
