Laser cutting is a technology that uses a laser to cut various materials, primarily used in industrial manufacturing. This process involves directing the output of a high-power laser through optics. The laser beam is focused on the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.
Laser cutting involves several key steps and components:
The laser source generates a high-intensity beam of coherent light, typically produced by a laser resonator. This beam can be in various forms such as CO2, fiber, or Nd:YAG lasers, each suitable for different materials and applications. The beam delivery system directs the laser beam from the source to the cutting head using a series of mirrors or fiber optics. This ensures the beam remains focused and precise as it reaches the material.
The cutting head contains lenses and mirrors that focus the laser beam to a fine point. This focused beam is powerful enough to cut through the material with extreme precision. The cutting head can also include nozzles that direct assist gases like oxygen or nitrogen to improve cutting quality and speed.
When the focused laser beam hits the material, it heats it to the point of melting, burning, or vaporizing. The assist gas helps to blow away the molten or vaporized material, leaving a clean cut edge. The laser’s movement is controlled by CNC (Computer Numerical Control) systems, which follow a programmed path to produce intricate shapes and patterns.
