Solid model reconstruction and feature recognition for mechanical part based on slice images

This paper presents an algorithm to reconstruct the three dimension solid model and recognize the features for mechanical part based on slice images. Its procedure includes: Step 1: The geometric types and parameters of surfaces are firstly identified according to the contour edges of slices; Step 2: The three dimension solid model of part is then reconstructed by constructing volume-cell, splitting end-face of volume-cell and bonding volume-cells; Step 3: Feature is recognized in the progress of solid model reconstruction through identifying and combining the positive feature, class-A and class-B negative. Finally, an example shows the effectiveness of the method.
