Title:
PROJECTION POLISHING SYSTEM, PROJECTION POLISHING METHOD, AND METHOD FOR MANUFACTURING STEEL PRODUCT
Document Type and Number:
WIPO Patent Application WO/2024/080081
Kind Code:
A1
Abstract:
A projection polishing system comprises: a shape measurement device (3) that measures a three-dimensional shape and orientation of an object material; a projection detection device (4) that detects a projection that is present on a surface of the object material and recognizes the position and shape of the projection; a polishing device (7) provided with a polishing tool for polishing the projection; and a polishing tool control device (5) that calculates a trajectory for movement of the polishing tool on the basis of the measured three-dimensional shape and orientation of the object material, and the detected position and shape of the projection, and controls the polishing device so that the polishing tool moves along the trajectory while changing the angle of contact of the polishing tool with the projection.
