The Reconstruction of Numeric Tooth Surface of the Spiral Bevel Gear by Using UG/Open GRIP

The algorithms for the surface reconstruction of the numeric tooth surface of the spiral bevel gear from numeric emulation were presented.The tooth surface extraction algorithm was discussed which is used to eliminate unnecessary grid data,the surface partition algorithm was presented to organize the extracted surface into B-spline array for further processing,and the algorithm of surface reconstruction based on UG/Open/GRIP,the redevelopment tool for UG,were put forward which are used to exchange the reconstructed surface data into Unigraphics.Practice shows that the algorithms are efficient and reliable for numeric tooth surface reconstruction.
