AI Technical Summary
Modern laser processing heads suffer from reproducible beam position errors due to mechanical, thermal, and manufacturing-related factors, leading to high manufacturing costs and potential damage to tools and workpieces.
A method to detect and compensate for positional changes of optical elements in the laser beam path by adjusting their position or tilt before and during processing, using a control system to store and apply correction values, allowing for less stringent manufacturing tolerances and reducing the need for manual adjustments.
Enables cost-effective production of laser machines with improved beam position accuracy and reduced mechanical errors, ensuring precise focus point positioning despite thermal and mechanical disturbances.
