A Machining Method of Sculptured Surface Based on the Quad-Tree Partition
The STL (Stereo Lithography) model is based on the triangular facets of 3D surface description model. This article studies the processing cutter path calculation of the STL model sculptured surface manufacturing: It proposes the full grid quad-tree partition method for surface of the triangular grid model. The sculptured surface is classified by quad-tree partition with projection plane for cutter location point calculation to give a fast search algorithm. Take tooth surface for example, the feasibility of the algorithm is verified according to the study of cone-shaped cutter tool path generation algorithms and also by the grinding test.
