Laser cutting is one of the most innovative and efficient technologies in modern industry, enabling extremely precise cutting and engraving. However, laser cutting is not a stand-alone technology; a number of related technologies and processes support and optimise it. Below we present these related technologies, which contribute significantly to the efficiency and quality of laser cutting.
1. CNC (Computer Numerical Control) Technology
CNC technology plays a fundamental role in laser cutting. The CNC control of laser cutting machines makes it possible to cut out extremely accurate, automatic cutting patterns and shapes. CNC systems allow complex geometries, patterns and lettering to be programmed, which significantly increases production efficiency and reduces the occurrence of errors. Precision control ensures that the cut shapes during laser cutting match the design specifications perfectly.
2. Oxy-Fuel Cutting and Plasma Cutting
Oxy-fuel cutting and plasma cutting are traditional technologies that can complement laser cutting in certain applications. Oxy-fuel cutting is suitable for cutting metals of greater thickness, while plasma cutting offers a fast and efficient solution for thicker plates. These technologies are often used in the pre- and post-processing of laser cutting, where laser cutting would not be economical or practical.
3. Waterjet Cutting
Waterjet cutting is another alternative technology that can complement laser cutting. In waterjet cutting, a high-pressure jet of water, often combined with an abrasive material, cuts through the material. This technology is particularly useful for cutting materials that a laser cannot process efficiently, such as thick ceramics or composite materials. Using waterjet cutting alongside laser cutting broadens the range of materials that can be processed.
4. Laser Sources and Optical Systems
The quality and efficiency of laser cutting depend to a great extent on the laser sources and optical systems. CO2 laser sources and fiber lasers each have different advantages. CO2 lasers have traditionally been used for cutting non-metallic materials such as wood and plastic, while fiber lasers are optimised specifically for cutting and engraving metals. Optical systems, such as lenses and mirror assemblies, ensure the precise focusing of the laser beam, which is essential for accurate cutting and engraving.
5. Design and Simulation Software
The software used before laser cutting is crucial in the design and simulation processes. CAD (computer-aided design) software makes it possible to create complex shapes and patterns digitally, while CAM (computer-aided manufacturing) software ensures that the designs are executed by the machine. Preliminary simulations help to foresee the cutting process, minimising errors and optimising the production process.
6. Extraction and Cooling Systems
The heat and fumes generated during laser cutting can cause problems, so the use of suitable extraction and cooling systems is essential. Extraction systems remove the fumes produced during cutting and the material particles coming out of the kerf, while cooling systems ensure that the laser and the associated mirror systems do not overheat. These technologies help maintain cutting quality and extend the service life of the machine.
7. Automated Material Handling Systems
Automated material handling systems, such as robots and conveyors, improve the efficiency and precision of laser cutting. These systems allow materials to be loaded and unloaded quickly and accurately, reducing labour requirements and increasing production speed.
Summary
The related technologies used in the laser cutting process not only improve cutting quality and precision, but also significantly increase production efficiency and flexibility. From CNC control through laser sources and optical systems and waterjet cutting to automated material handling systems, every single technology contributes to the best possible performance of the laser cutting process. In the future, continuous innovation and development may further increase the efficiency of these technologies, opening the way to new fields of application.
