In this paper, we propose a method that uses a 3D scanner to efficiently turn a large backup roll weighing 50–60t from a free forged material. The material was prepared through free forging on a 17,000-t press; the machining allowance was large and the distribution was uneven. Previously, skilled workers visually checked the shape of the material and manually performed roughing, which is a bottleneck in which machining defects often occur. In this study, a 3D shape model was created through 3D scanning of the procedure to determine the centerline of the workpiece and create an efficient tool path for CNC rough turning. The proposed method was applied to four products; the machining time was reduced by 35.7%, and no machining defects occurred thus far. The proposed method can be used to process not only backup rolls but also large rotating parts such as turbine shafts.
