WIPO Patent Application WO/2021/200654

A1

The purpose of the present invention is to easily estimate the tool state from an image of a machined surface.　A tool state learning device is provided with: a storage unit for storing an arbitrary image captured by an imaging device imaging a machined surface of an arbitrary workpiece cut using an arbitrary tool; a teacher data acquisition unit for acquiring, as input data, an arbitrary image stored in the storage unit, and acquiring, as a label, the state of the tool annotated according to prescribed levels indicating the degree of wear of the tool on the basis of the arbitrary image; and a tool state learning unit for using the label and the input data acquired by the teacher data acquisition unit to perform supervised learning, and generating a learned model in which a machined surface image of the machined surface of a workpiece imaged by the imaging device is inputted and the state of the tool that cut the machined surface of the workpiece is outputted.
