Aim: To optimize the laser cutting process for glass components used in metrological equipment, enhancing precision and reducing defects such as crack formation at stitching interfaces.
Brief description: In collaboration with Precizika Metrology, this project focused on refining laser bottom-up cutting techniques utilizing femtosecond lasers. The primary challenge addressed was the occurrence of cracks at the stitching interfaces during the cutting process. By experimenting with different stitching strategies, including increasing the stitching angle to 15 degrees and modifying the chamfer formation to overlap with the cut stitching area, the project aimed to achieve clean cuts without compromising the structural integrity of the glass components.
Benefits: Implementing the optimized stitching strategy resulted in successful cuts with no crack formation at the interfaces. This advancement enhances the quality and reliability of glass components in metrological equipment, leading to improved performance and longevity. The refined process also contributes to increased efficiency in manufacturing, reducing material waste and the need for rework.
