Optimizing Motion Synchronization in Digital Photonics Production: Strategies for Enhancing Efficiency and Quality in Laser Material Processing

Digital Photonics Production (DPP) discusses the relation between costs, complexity and product improvement compared to conventional production. One interesting case study for DPP is the combination of a 2D galvanometer scanner head and XY servo stage, which stands out as a traditional method for laser material processing with solid applications. A recent approach of motion synchronization between both devices has brought a significant enhancement in the production, since it can reduce execution time and raise processing quality compared to traditional asynchronous techniques. On the other hand, splitting the motion between both devices is still a challenge. The aim of this paper is to succinctly summarize and review different strategies that can be employed to compute the trajectories for the scanner and stage. The focus of the addressed techniques is to describe methods to synchronize the motion while simultaneously considering the kinematic constraints of each device. Furthermore, this paper discusses the relation complexity and improvement of each technique in the context of DPP and finally presents the relevant requirements of trajectory planners for laser processing. 14 ale Photonische Produktion T Christian Hinke
