Shell Surface Reverse Engineering Based on Pro/E 4.0

This paper presents a non-cable nail's shell surface reversal,and studies the method of the exact reconstruction of the complex shell surface.We collect the data of the complex surface of the shell by 3D coordinate measure machine,and process the data with Matlab software.Then with boundaries and N-side surface methodology,we construct the shell surface in Pro/E 4.0 software.Also we use ISDX curved module to analysis the shell surface,and to improve the shell surface,obtain a high-precision program for this kind of shell surface and realize the exact reconstruction of the complex shell surface.Finally,we sum up the method by which fewer points are used to construct complex shell surface.
