Laser cutting is a technology that uses a laser to cut materials with precision. It is a non-contact process that employs a focused laser beam to melt, burn, or vaporize material. The laser typically emits a coherent and concentrated light beam that is directed through a lens, focusing it onto a small spot.
Laser Cutting includes:
-
Laser System Setup
- Material Preparation
- Programming
- Calibration
- Focusing the Laser
- Cutting Process
- Controlled Movement
- Quality Control
- Cooling
- Post-Processing
Laser Generation
The process begins with the generation of a laser beam. The laser source, often a gas mixture or a fiber-optic medium, produces a concentrated and coherent beam of light.
Material Alignment
The material to be cut is positioned on a movable platform. The alignment of the material is crucial, and precision is often achieved using computer-controlled systems.
Cutting Process
The high-energy laser beam melts, burns, or vaporizes the material along the predefined cutting path. Computer numerical control (CNC) systems guide the laser cutter.
Beam Focusing
The laser beam is directed through a series of mirrors and lenses to focus it into a small, intense spot.
Material Interaction
As the focused laser beam makes contact with the material's surface, it rapidly heats or vaporizes the material.
Waste Removal
The excess material, in the form of molten or vaporized material, is removed by assist gases. The finished product is ready for use or further processing.
