Guaranteeing the machining accuracy of a workpiece is difficult because of various factors. Typical causes of this problem include individual differences between the castings used as materials, tool deformation due to cutting loads, and inconsistencies between machine-tool machining programs. In some cases, these factors overlap. In this study, a mechanism that does not lose shape-data information generated from CAD and CAM before NC program execution is proposed to creates a product as close as possible to the original three-dimensional shape. The problems that can be solved via computerized numerical controller (CNC) are identified and a solution is proposed in the form of a shared database and data model acting as an information sharing basis for the integrated CNC system.
