Document Type and Number:
WIPO Patent Application WO/2020/105218
Kind Code:
A1
Abstract:
Provided is a method for measuring the precision of a machine tool, including a step for setting a workpiece in a machine tool and machining the workpiece, a step for setting a sensor in the machine tool, a step for measuring the same point on a machined surface of the workpiece in at least two measurement points in the field of view of the sensor, and a step for detecting the precision of the machine tool on the basis of the measurement results in the at least two measurement points. It is thereby possible to realize a measurement method relating to the mechanical precision of a machine tool, that can be performed in a small number of steps and at low cost without the use of a measurement standard.
