Laser cutting of metal - basic principles and applications

Laser cutting of metal is a process in which metal products are cut using a laser beam. Laser metal cutting in Moscow has become the most popular metalworking method in recent decades due to its high precision and efficiency.

Basic principles of operation

The principle of laser generation is based on the use of an active medium, which is excited by energy transferred by electrical discharges or other energy sources. This leads to the creation of light quanta, which are then amplified and emitted through the laser's output window as a laser beam.

The laser beam is focused using an optical system consisting of lenses and mirrors. They direct and focus the laser beam onto the metal surface, enabling high cutting precision.

The laser beam interacts with the metal through absorption and reflection. The metal absorbs the laser radiation, causing it to heat up and melt. The thermal action on the material creates a cut, which can then be continued by moving the laser head.

The laser head is moved and controlled using a coordinate system and software control. Precision and speed play a crucial role in the cutting process, as they impact the quality and productivity of the work.

Technical aspects of laser cutting of metal

Selecting optimal cutting parameters is a key aspect of laser metal cutting. The laser beam's power and energy density must be selected to achieve the required cutting depth and minimize potential material deformation. The laser head's travel speed also affects the cut quality, as too high a speed can result in uneven cuts.

The advantages of laser metal cutting include high precision and cleanliness. The laser beam can process complex shapes and create small holes, making it an ideal tool for metal fabrication. Furthermore, laser metal cutting can process a variety of materials, including steel, aluminum, copper, and more. This makes it a versatile tool for a variety of industries.

However, laser cutting of metal also has its limitations. The thickness and size of the parts being processed can impact laser cutting capabilities. Also, some materials may be more difficult to laser process due to their properties, such as high thermal conductivity.

Applications of laser cutting of metal

Laser metal cutting has practical applications across a wide range of industries. In metal manufacturing, it is used to create parts and components with high precision and quality. In the automotive and aviation industries, laser metal cutting plays a key role in the production of body parts, as well as in the creation of complex engine and turbine components. In mechanical engineering and electronics, it is used to process metal parts and printed circuit boards.

The future of laser metal cutting promises new technologies and developments. With the advent of more powerful and efficient laser sources, metal cutting capabilities will expand. Research in optical focusing systems will also enable even greater precision and cutting quality.

The future of laser metal cutting promises new technologies and opportunities to improve productivity and quality. The development of automated control and monitoring systems, as well as research into optical focusing systems, will further advance this process.

Is laser cutting of metal harmful to humans?

One of the main advantages of laser metal cutting is its environmental friendliness. Unlike other cutting technologies, it does not use chemical reagents or solvents, making it more environmentally friendly and safer for both the environment and operators.

Laser cutting is one of the safest metalworking methods. During the process, workers are not exposed to the risk of mechanical injury from machine cutting elements, metal shavings, or abrasive streams. All these potential harms are eliminated due to the specific nature of laser cutting. Although hot metal is present, a jet of compressed gas directs the molten metal in a precisely defined direction, preventing it from coming into contact with people.
