Working principle of laser cutting machine：
A laser cutting machine operates based on the principle of using a highly focused beam of light, known as a laser, to cut materials with precision and accuracy. Here is a detailed description of its working principle:
- 1.Laser Generation: The laser cutting machine starts by generating a laser beam using a laser resonator. This resonator contains a gas mixture, such as carbon dioxide (CO2), nitrogen (N2), and helium (He), which, when energized, produces a highly concentrated beam of light.
- 2.Beam Amplification: The laser beam is then amplified within the resonator by passing it through a series of mirrors and lenses. These optical devices intensify the laser's power, increasing its energy density and enabling high cutting speeds.
- 3.Beam Delivery System: The amplified laser beam is delivered from the resonator to the cutting head through a beam delivery system. This system typically consists of mirrors and fiber optics, which help guide and direct the laser beam to the desired cutting location.
- 4.Material Interaction: When the laser beam reaches the cutting head, it is focused into a small spot size, ranging from a few micrometers to a few millimeters, depending on the application. The focused laser beam is then directed onto the material to be cut, which could be metal, wood, plastic, or various other materials.
- 5.Material Absorption: The material being cut absorbs the energy of the laser beam. This energy is converted into heat, causing the material to melt, vaporize, or undergo a process known as thermal stress cracking. Different materials respond differently to the laser beam, and adjustments can be made to the beam's power and speed to optimize the cutting process for each material.
- 6.Cutting Process: As the laser beam interacts with the material, it moves along the desired cutting path. The focused laser beam acts as a high-energy heat source that effectively melts or vaporizes the material within a narrow region. As the laser continues to move, it creates a kerf (cutting groove) through the material, separating it into two distinct pieces.
- 7.Gas Assist and Removal: To improve the cutting process and remove molten material, a gas assist system is often used. This system blows a gas, typically compressed air or nitrogen, onto the cutting area, helping to remove debris and prevent the accumulation of molten material. Gas can also prevent oxidation reactions and enhance the edge quality of the cut.
- 8.CNC Control: Laser cutting machines are usually equipped with computer numeric control (CNC) systems. These systems use specialized software to precisely control the movement of the laser beam and the cutting head. The CNC system takes input from CAD/CAM software, allowing for highly accurate and complex cutting patterns.
