摘　　要：因头戴式智能眼镜轻量化、小型化等需求,高分子材料逐步导入应用,但是因注塑过程中模具精度与材料收缩等因素,容易造成零/部件坯料的三维模型与注塑实物尺寸不匹配的问题,从而引起五轴联动激光设备切割眼镜零/部件尺寸超差。针对此问题,借助于ATOS光学扫描仪,分析了注塑产品的三维模型与实物的尺寸误差,通过对注塑产品零/部件进行逆向工程建模,验证了在扫描生成三维模型上提取刀路轨迹进行五轴联动激光切割的可行性,为提高三维模型与注塑实物尺寸不匹配产品的五轴联动激光切割精度提供了一种解决思路。Due to lightweight,miniaturization and other needs of head-mounted smart glasses,polymer materials are gradually introduced into the application,but due to factors such as mold accuracy and material shrinkage during the injection process,it is easy to cause the problem of mismatch between the 3D model of the spare parts and the real thing,which causes the size of the five-axis laser linkage cutting glasses parts to be out of line.In order to solve this problem,the dimensional error between the three-dimensional model of injection products and the real objects is analyzed with the help of ATOS optical scanner.Through reverse engineering modeling of injection product parts,it verifies the feasibility of extracting the tool path trajectory for five-axis laser cutting on the three-dimensional model generated by scanning,which provides a solution to improve the precision of 5-axis laser cutting for products that do not match the three-dimensional model and the injection molding size.
