A novel wedges-based laser optomechanical system 2D motion control inverse kinematic algorithm

This paper introduces an innovative wedge-prism-based 2D laser scanning optomechanical system, complemented by an inverse kinematic algorithm that revolutionizes the manufacturing of irregularly shaped trajectories. Based on inverse kinematic analysis of laser beam transmission trajectories, our model presents a novel approach to precisely control the focused laser spot within a two-wedge system. Initially, we utilize image recognition to capture the contour of the desired machining trajectory, transforming it into processing point coordinates. The transition to a polar coordinate system streamlines calculations, allowing for accurate determination of the wedges’ rotational positions at each stage of the machining process. We conduct comparative analyses of various machining results, discussing their implications in relation to experimental outcomes, all grounded in optimization strategies for processing points. A standout feature of our study is the elimination of the need for additional motion control modules, enabling seamless integration of optical equipment into existing helical drilling systems. This integration not only reduces overall system costs but also significantly enhances processing efficiency and effectiveness in creating micro holes and intricately shaped structures. Our findings pave the way for more versatile and efficient laser machining solutions in advanced manufacturing applications.
