TECHNOLOGY OF FREE-FORM SURFACE GEOMETRICAL MODELSRECONSTRUCTION BASED ON B-SPLINE

摘要

The paper used the B-Spline as the approach of surface construction; Developed a reconstruction system offree-form surface , Made some experiments of reconstruction the geometric model of free-form surface by usingdiscrete data acquired from coordinator measurement machine. With the reconstruction system of free-form surface,output the data that required by CAD/CAM software to construction the geometric surface and reconstructed thesame type surface by using different CAD/CAM system (example: I-DEAS and AutoCAD); And developed approachof sharing the information and data in multi-location collaboration design in a different platform environment basedon Internet/Intranet. And the geometrical free-form surface models may be used to manufacturer in CNC system.
