  • Patent number: 9724801
    Abstract: A deburring device includes a deburring tool for removing burrs from an object, a robot for moving an object or the tool, a force sensor for detecting force acting on the tool, and a visual sensor for detecting a position of a burr portion of the object. According to the deburring device, information regarding shape data of the burr portion and a posture of the tool is obtained beforehand based on three-dimensional data of the object. Based on the shape data and the posture of the tool, a robot program is created. In accordance with an actual burr portion detected by the visual sensor, the robot program is replaced as necessary. During the deburring, the robot is controlled according to the force control by using a detected value from the force sensor.
