  • Publication number: 20230407594
    Abstract: A contact of an attachment with an obstacle is suppressed, and concurrently, a wasteful motion of the attachment is suppressed. When determining that an obstacle specific portion exists between a start point and an end point, a controller sets an avoidance path as a target path. The avoidance path is a path along which an attachment specific portion moves from the start point to the end point while the attachment is led to an avoidance operation of avoiding the obstacle. When determining that the obstacle specific portion does not exist between the start point and the end point, the controller sets a non-avoidance path as the target path. The non-avoidance path is a path along which the attachment specific portion moves from the start point to the end point while the attachment is not led to the avoidance operation.

    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.
