Most future industrial applications of USP lasers require high processing quality, but also higher throughput and productivity, for example with higher average powers and more advanced processing strategies. We provide a description of a built-in functionality enabling synchronization of multiple mechanical (rotary and linear) and optical axis to enhanced engraving and texturing operation over 3D surfaces. Thanks to a closed loop regulation of the scanner over the mechanical axis encoder, the energy distribution is maintained constant and homogeneous during machining. The functionality is fully integrated into LASEA KYLA® and LS-CAM software allowing us to easily generate complex machining with multiple input formats (DXF, STL, Greyscale). Thanks to the simultaneous and synchronized motion between mechanical and optical axis, large machining areas can be processed without discontinuities in the pattern, which are known, for instance, to impact the quality and the final product performance. This processing method also optimize the thermal management of laser machining compared to more conventional sequential positioning methods. This important aspect paves the way for increased productivity thanks to the increase of laser power and scanning speeds in industry. We provide a new solution for optimized cycle time and machining quality, demonstrated onto parts with a revolutionary geometry.
