Die and mold are the most effective method for manufacturing parts. After a die or mold is used for a long time, it can be deformed or worn down or partly damaged. For the cases, it is welded with additional materials to be machined in repairing area with the original NC data for initial machining. However, this repairing process may cause microdrops at the boundary of repair machining area, since the used die might be deformed due to various reasons including residual stress or heat stress by welding, in addition to the error from the setup for the repair machining. This study is to develop a method to generate adapted NC data for repairing a deformed die, which can reduce the microdrops at the border of repair machining area. As a result, it cannot only negate or minimize the time and cost for removing the microdrops on repaired die surface but also can improve quality of the final products. Even though the proposed method was applied to dies for car body parts, it is not limited to the auto industry but can be extended to the other die and mold industries.
