  • Publication number: 20230330802
    Abstract: A flaw grinding system, a flaw grinding method, and a steel-product manufacturing method enable automation of the task of grinding a flaw on the surface of a workpiece having a three-dimensional shape, while also reducing the occurrence of faulty grinding such as over-grinding or under-grinding. The flaw grinding system includes a grinding apparatus, a shape measurement apparatus, a flaw detection apparatus, and a grinding-tool control apparatus. The grinding apparatus includes a grinding tool that grinds a flaw on a surface of a workpiece. The shape measurement apparatus measures a three-dimensional shape and an attitude of the workpiece. The flaw detection apparatus detects a location of the flaw on the workpiece. The grinding-tool control apparatus generates a trajectory of the grinding tool to grind the flaw. The grinding-tool control apparatus controls the grinding apparatus in a manner that causes the grinding tool to move along the trajectory.
