WIPO Patent Application WO/2019/176773

A1

[Problem] To provide a wear amount estimation system, a correction system, a fault detection system, a service life detection system, and a machine tool and wear amount estimation method for improving the accuracy of the estimated wear amount of a tool. [Solution] This wear amount estimation system is a system for estimating the amount of wear of a tool in a machine tool whereby workpieces having the same specifications are repetitively machined using the tool under the same conditions, wherein said system comprises a calculation unit that calculates A and α in a relational expression expressed by, e.g., W = Atα, where W is the amount of wear of the tool from the start of machining with the tool, t is the elapsed time, and A and α (< 1) are constants, the calculation being made on the basis of a plurality of measured values of the amount of wear of the tool with respect to the time elapsed from the start of machining with the tool.
