3D part contour curves matching algorithm is an important content in panel die-face design based on template. By researching on the existed 3D curves matching algorithm, according to the feature of complex part contour curve, 3D part contour curves matching algorithm was advanced. This algorithm was based on the skills of multiscale filter, feature calculation, partition equivalent class by Hausdorff distance, and the ISODATA cluster analysis method of calculating the best matching switch matrix was put forward. The corresponding programs were developed. The algorithm was demonstrated to be efficient, robust and fault tolerant by three typical examples of actual parts which are the selfsame, different in size and little change in shape.
