Practical application of AI in laser cutting machines

Laser cutting technology is rapidly iterating from traditional manufacturing to intelligent manufacturing through the deep empowerment of AI. The following are the core application scenarios and typical cases of AI in laser cutting machines:

1. Intelligent identification and classification of materials

SensiCut system (CSAIL laboratory, Massachusetts Institute of Technology):

- **Technical principle**: Through the combination of **speckle sensing** (using laser to detect the microstructure of the material surface) and **deep learning** (training more than 38,000 material images), it can accurately identify 30+ materials (such as acrylic, foam board, styrene, etc.).

- **Practical value**: Avoid the release of harmful gases or cutting failures caused by misjudgment of materials, and reduce the scrap rate by more than 20%, especially suitable for scenes that are difficult to distinguish with the naked eye, such as transparent materials (such as mask production).

- **Industry case**: In Gangchun Laser Technology's **AI intelligent assembly line** patent (CN119282361A), AI automatically matches the feed roller group and cutting parameters through visual sensors to achieve dynamic adaptation of material classification and process parameters.

2. Cutting path optimization and parameter adjustment

- **Dynamic path planning**:

- In the patent of Boou Laser (CN118789136A), the AI algorithm combines the slide movement data to optimize the cutting path in real time, and improve the cutting efficiency of complex shapes by 15%-30%.

- Wuhan Aosi patent uses AI to analyze the material thickness and hardness, automatically generates the **minimum heat affected zone path**, and reduces the risk of metal deformation.

- **Parameter adaptation**:

- In the portable device of Saibo CNC (CN222133824U), AI adjusts the laser power and cutting speed in real time according to the ambient temperature and humidity and material status to ensure that the cutting accuracy is stable within ±0.1mm.

3. Real-time monitoring and quality control

- **Abnormal detection system**:

- In the patent of Haikou Bogu's straightening device, AI analyzes the vibration data of the slide rail to warn of mechanical deviation in advance, shortening the downtime of equipment failure by 40%.

- **Visual quality inspection**: Some manufacturers integrate AI cameras to monitor the quality of the cutting section (such as burrs and slag) in real time, automatically mark defective products and trigger the rework process.

4. Automated assembly line integration

- **Gangchun Laser's AI assembly line**:

5. Safety protection and risk warning

- **Hazardous material interception**:

The SensiCut system can identify chlorine-containing/fluorine-containing materials (such as PVC), automatically prohibit cutting or trigger exhaust purification devices to prevent the release of toxic gases.

- **Operational safety protection**:

AI uses infrared sensors to monitor the approach of personnel and triggers the laser emergency stop within 0.3 seconds, reducing the accident rate by more than 90%.

6. Design generation and personalized customization

- **AI-assisted design tools**:

- Tools such as Sohu Simple AI automatically generate cutting drawings by inputting text descriptions (such as "coffee shop logo, blue coffee cup"), accelerating the entire process from design to production.

- Case: A cultural and creative enterprise uses AI to generate complex hollow patterns, and the cutting time is shortened from 8 hours of traditional design to 2 hours.

7. Future trends

- **Deep integration direction**:

- **Digital twin**: Build a virtual cutting environment, AI simulates the cutting effects of different parameter combinations, and optimizes the trial and error cost.

- **Edge computing**: Deploy lightweight AI models on the device side to achieve millisecond-level response (such as real-time compensation of sudden material deformation).

- **Industry impact**:

It is expected that by 2026, AI-driven laser cutting equipment will cover more than 60% of high-end manufacturing industries, increasing the overall performance of a single device by 50%-200%.

**Summary**: AI is reconstructing the "perception-decision-execution" closed loop of laser cutting, from material identification to process optimization, from safety protection to design innovation, and comprehensively promoting the industry to develop in the direction of efficiency, precision and safety. If companies want to maintain their competitiveness, they need to focus on the integrated application scenarios of AI and laser cutting.
