Free-form surface rebuild using an abductive neural network

This study uses an abductive neural network in free-from surface rebuild in reverse engineering. The calculation of the network structure and error and the accuracy assigned to the network physically, in order to rebuild a free-form surface, are discussed. An abductive neural network is used to establish the surface parameter equation, the result showing that it is capable of accuracy in predicting the control point of the surface coordinate and any points on the surface. Further, it is capable of being applied in the development of an industrial product and in facilitating the modification of the product, and in the planning of a CAM path.
