激光纹理化是一种相对较新的多工艺技术，已用于加工3D曲面，在注塑模具3D曲面上创建装饰性纹理，可以更灵活、更高效地提高表面质量，实现塑料成型件的美观表面。针对传统的纹理化加工方法在注塑模表面纹理化过程中容易产生较大变形的问题，提出了一种基于三轴振镜扫描单元的三维曲面激光纹理化加工方法。该方法是基于计算机纹理映射技术的。纹理映射算法包括曲面三角剖分、标记、变形测量、控制和数值方法。建立了一个计算机纹理映射接口，实现了将二维原始纹理应用到曲面上，控制三维纹理数学模型畸变率的纹理映射算法。通过对鼠标顶盖注塑模大曲率曲面激光毛化的实例研究，表明该方法满足注塑模激光毛化的质量要求。
Laser texturing is a relatively new multiprocess technique that has been used for machining 3D curved surfaces; it is more flexible and efficient to create decorative texture on 3D curved surfaces of injection molds so as to improve the surface quality and achieve cosmetic surface of molded plastic parts. In this paper, a novel method of laser texturing 3D curved surface based on 3-axis galvanometer scanning unit has been presented to prevent the texturing of injection mold surface from much distortion which is often caused by traditional texturing processes. The novel method has been based on the computer texture mapping technology which has been developed and presented. The developed texture mapping algorithm includes surface triangulation, notations, distortion measurement, control, and numerical method. An interface of computer texture mapping has been built to implement the algorithm of texture mapping approach to controlled distortion rate of 3D texture math model from 2D original texture applied to curvature surface. Through a case study of laser texturing of a high curvature surface of injection mold of a mice top case, it shows that the novel method of laser texturing meets the quality standard of laser texturing of injection mold.
