What is the working process of laser engravers?

The laser engraving process is the process by which the machine cuts the design into the surface of the material. Although this process may vary by laser engravers, it follows several general steps. Check out the laser engraving process overview to learn more about how laser engravers work:

Operators make design
Before laser engravers can engrave material, the machine operator must enter the design into the control system. Laser engravers use automation and computer software to convert designs such as logos or barcodes into the movement of the laser across the surface of the material. Some laser engravers can store hundreds of designs, making it easier for manufacturers to achieve peak efficiency.
Operators place objects
After the laser engravers receive the design, the operator must place the material in the correct position for engraving. Usually, smaller materials can go into the laser tray. Larger workpieces may require larger surfaces. Many laser engravers can be integrated into the production line for easy engraving.
Operators complete the settings
The operator ensures that the final settings on the machine are correct for the material and the desired engraving pattern. The laser must be focused on the workpiece. The operator then selects the desired engraving settings, including depth and beam power. These settings will depend on the material and the laser engraving pattern chosen by the operator.
Machines start the laser
Once the operator finishes setting up the machine, the machine uses software to activate the laser to start carving. The laser passes through the material throughout the engraving process, carving deep marks with high contrast that remain clear even in harsh conditions.
Materials are processed
After the laser finishes engraving, the operator removes the material from the machine for further processing. After removing the top layer of the material, sublimation creates residues such as metal fragments and soot. The material must be treated to remove these residues. Some applications may use shot peening or heat treatment to eliminate irregularities.
