Abstract

Recent experiments with newly developed radial machining paths have shown that process time gains of up to 300% can be achieved compared to conventional linear scanning strategies. Various radial patterns such as circles and spirals were analyzed and developed. These individual methods were further optimized to achieve the highest possible process speeds and reduce downtime when the laser is not in operation. Furthermore, an optical z-axis was integrated into the system, which allows the marking of workpieces with uneven surfaces while maintaining full synchronization between the scanner and the laser system.
