<p>The surface of a clay model (50) is laser scanned (52) to obtain a set of laser scan data. A first algorithm (56) implemented at an engineering workstation is used to create a first set of equations which represent a three-dimensional surface of the model from the edited set of scan data. A second algorithm (58) uses known wire frame data for the part model to compute a second set of mathematical equations. The first and second set of equations represent surfaces and characteristic(s) of the model in a recorded format usable by CAD-based systems to facilitate part design and tool construction. A third algorithm (60) generates an NC tool path data from the first and second set of equations. The NC tool path data may be used at a machining center (62) to cut a production part mold (64), or a direct reproduction of the model.</p> |
