It have been composed only introducing automatic equipment without analyzing manufacturing process in many smart factories; hence, productivity does not improve significantly. In this study, production data obtained from a computerized NC machining center were analyzed based on the operation and tool costs for each process to reduce the tool management cost of the cutting process for the die manufacturing, which is weak in cost analysis. Tool cost of the minimum cost required for each process was then modeled using linear programming. We derived a modeling logic that could manage the life of the medium cutting process using the programming method and achieved a cost reduction of up to 12% compared to the operation cost by linking tool cost to the manufacturing per process cost. The proposed algorithm can be applied to field equipment as a manual cost item one of the items of the FOM which manufacturing optimization system.
