Casting Mould Design and Manufacture with Reverse Engineering Technology

A novel manufacture processing of the engine gas-guide casting mould is presented in this thesis. The surface digital data of gas-guide is obtained by reversing engineering technology, and is processed in CAD environment to establish its three-dimension mold, finally the mould is manufactured through CAM system. The results indicate that this procedure integrating reverse engineering and NC technology can considerably advance the machine precision, reduce cost of the product, shorten manufacture cycle of mould and improve the quality of the product.
