Abstract
The present invention provides an improved method for defining complex geometries to transpose geometric surfaces accurately into tooling. The method for entering accurate position data defining geometric surfaces eliminates the entry of erroneous position data at the sharp edges and boundaries of geometric shapes, such as the intersections between geometric tooling surfaces and planar parting surfaces. The method further provides for the creation and interrelation of accurate design, manufacturing, and control data bases which are used to enhance the speed and accuracy with which tooling having geometric surfaces may be designed and produced. The method of the present invention further has a reverse engineering capability which accommodates design improvements, facilitates correction of manufacturing errors in tooling, and permits monitoring and repair of tooling wear more quickly and easily than known methods.
