AI Technical Summary
Technical Problem
During high-power laser cutting, the cutting head lens deforms due to high temperature, causing focal length shift and resulting in inconsistent cross-sectional effects when cutting large contour parts.
Method used
By automatically generating a focus compensation data table, focus compensation is performed based on the opening time, including axis focus compensation and pre-focus compensation. The focal axis is adjusted to eliminate focus shift caused by lens deformation, thereby achieving consistent cutting results.
Benefits of technology
A convenient and efficient focus compensation method is provided, which eliminates lens deformation caused by high temperature and significantly improves the consistency of cutting effect.
