针对注塑机螺杆结构复杂、形状精度要求高、优化设计周期长等问题,运用逆向建模方法,利用Win3D型三维扫描仪及Geomagic Wrap软件采集该注塑机螺杆的点云数据,将其封装为曲面,导入逆向建模软件Geomagic Design X中,高精度创建其三维数字化模型,为注塑机螺杆的优化设计提供高精度模型。经误差分析软件Geomagic Control的检测,注塑机螺杆的逆向模型误差不超过0.02 mm,满足工业设计要求。

In view of the complicated structure of the injection molding machine screw,its shape of high accuracy requirements and long cycle of optimization design,by reverse modeling method and with the Win3D three-dimensional scanner and Geomagic Wrap software,the point cloud data of the screw of the injection molding machine is collected,encapsulated into a curved surface and imported into the reverse modeling software Geomagic Design X to create its 3D digital model with high precision and provide high-precision model for the optimized design of the injection molding machine screw.The error analysis software Geomagic Control shows that the error of the reverse model of the injection molding machine screw does not exceed 0.02 mm,which meets the needs of the industry.
