Preparation and Setup:

• Before engraving, the operator prepares the machine by ensuring it is properly installed and calibrated. The workpiece material (e.g., metal, plastic) is selected, and the laser engraver is configured based on the material’s properties and the desired engraving depth.
• The 3D fiber laser engraver is equipped with software (such as Eastern Logic 3DS) that allows the user to design and import 3D models or graphics. The user loads the design file into the software and adjusts the settings for engraving, such as power, speed, and focus.

Material Positioning:

• The workpiece is securely placed on the workbench of the laser engraver. For accurate results, it is crucial to ensure the material is positioned flat or at the desired angle if working on curved or irregular surfaces.
• The integrated aluminum workbench of the Kirin Laser machine provides multiple flexible screw holes for easy fixture mounting, keeping the workpiece stable during engraving.

Dynamic Focus Control:

• The 3D fiber laser engraver uses a dynamic focus system to maintain consistent laser focus on varying surface heights. This is crucial for 3D engraving, where the surface is not flat.
• In Kirin Laser’s engravers, the Sino-galvo dynamic focus system controls the galvo head, dynamically adjusting the focal length to maintain precision across complex surfaces such as slopes, steps, or cones.

Galvo Head Operation:

• The galvo head, integrated with advanced 3D Sino-galvo scanner technology, quickly directs the laser beam across the work surface with high precision. The galvo mirrors move in the X and Y axes to guide the laser beam accurately over the workpiece.
• The dynamic Z-axis operates in tandem with the XY-axis to manage the height variations, ensuring distortion-free engraving on 3D surfaces.

Laser Engraving Process:

• Once the laser settings are configured, and the workpiece is in place, the operator initiates the engraving process through the software. The fiber laser then emits a high-intensity laser beam that interacts with the surface of the material.
• The laser beam removes material in a controlled manner to engrave the desired patterns, text, or images. For deep engraving or relief work, multiple passes may be needed, and the software will control the depth incrementally.

Monitoring and Adjustments:

• The engraving process can be monitored in real-time, allowing the operator to make any necessary adjustments to the laser power, speed, or focus. Advanced software interfaces provide a visual guide to ensure that the laser is following the 3D contours accurately.
• If required, adjustments can be made to the focal length or laser parameters to enhance the quality or depth of the engraving, especially for complex geometries or varying surface levels.

Finishing Touches:

• After the engraving process is complete, the workpiece is inspected for quality and precision. If additional engraving is required, the operator can re-align the workpiece and repeat the process.
• For certain materials, a post-engraving cleaning process might be necessary to remove debris or residue from the engraved surface to enhance clarity and appearance.

Software Post-Processing:

• After engraving, the software can also assist in post-processing tasks such as checking the alignment, verifying depths, and ensuring that all markings meet the required standards.
• This is particularly important for applications in industries like aerospace, automotive, and medical devices, where precision and compliance are critical.
