Document Type and Number:
WIPO Patent Application WO/2023/181476
Kind Code:
A1
Abstract:
A method for machining a workpiece (5) that is carried out by a machining system (1) has: a first step for finding a first error, which is a contour error of a tool found from an outer shape of a tool (3) as measured by a tool-shaped measurement device (31); a second step for finding a second error, where a machining error found from the shape of a machining surface of the workpiece (5) as measured by three-dimensional workpiece measurement devices (32, 51) has been converted into the contour error of the tool; and a third step where a movement means moves the tool (3) with the respect to the workpiece on the basis of a prescribed NC program. In the third step, the NC program corrects the position of the tool (3) on the basis of a combined error in which the second error has been added to the first error.
