Abstract:
Based on
NC track data of tool surface, an automatic quadrilateral mesh
generation method is proposed, This method first make use of maximum
deviation of chordal length to delete redundant points on NC track
curves, then redistribute points on curves according to approximate
feature of adjacent NC curves. Finally complete quadrilateral meshes are
generated. Numerical experiment is carried out to verify the validity
and efficiency of this method.
Key words:
Quadrialteral mesh metal forming Tool surface NC track
