In a groundbreaking advancement for the manufacturing industry, researchers have unveiled a sophisticated 7-axis on-the-fly laser surface texturing (LST) system tailored for complex curved surfaces. This innovative technology promises to enhance precision and efficiency in the functionalization of surfaces, a critical factor for various applications in construction and beyond.
The research, led by Wenqi Ma from the Center for Precision Engineering at Harbin Institute of Technology, addresses a significant challenge in the field: the intricacies of laser-matter interaction on continuously varying geometries. Traditional methods often struggle to maintain high levels of accuracy while processing complex shapes, leading to inefficiencies and potential errors.
“This new system integrates a 5-axis linkage motion platform with a 2-axis galvanometer, allowing for synchronized movement that significantly reduces following errors,” explained Ma. The development of an algorithm that decomposes spatial texture trajectories into low-frequency and high-frequency components is a key innovation, enabling the precise control of each axis in real time.
The implications of this technology are vast. In construction, where materials often feature intricate designs and curves, the ability to apply laser texturing with high fidelity can improve the performance of surfaces, enhancing durability and functionality. For instance, textured surfaces can lead to better adhesion in coatings, improved wear resistance, and even aesthetic enhancements that are increasingly demanded in modern architecture.
The experimental results demonstrate that the 7-axis system outperforms its 5-axis counterpart, achieving superior processing efficiency and texturing accuracy. “By minimizing the following errors associated with mechanical stages, we can achieve a level of performance that was previously unattainable,” Ma noted. This advancement not only streamlines the manufacturing process but also opens new avenues for innovation in product design and surface engineering.
As industries continue to seek ways to integrate advanced technologies into their operations, the findings from this research could shape the future of laser micromachining systems. The marriage of precision engineering and automation heralds a new era where complex surface treatments are not only feasible but also economically viable.
Published in the “International Journal of Extreme Manufacturing,” this research stands to make a significant impact on how industries approach surface functionalization. For more information on this pioneering work, visit the Center for Precision Engineering at Harbin Institute of Technology.
