Algorithmization Principles of Machining Datum Surface Select

With computer aided design process of mechanical-processing parts (CAD / CAM systems), the datum select is of great importance in terms of providing the required accuracy and the calculation of optimal allowances. While designing the algorithm for selecting, drawing appears as the basic element of procedure, so it is important to put all the manifold parts to rights, or to classify it. The structure of selection algorithm has been reduced to two successive interrelated branches that include the maximum unified sequence of blocks (stages). The algorithm is implemented in the program for the PC in the module "CAD drawing casting and tested on the castings in road parts.
