Machine learning device, cleaning prediction device, and cleaning system

Abstract

A machine learning device has an input data acquisition unit that acquires input data including an arbitrary machining condition for an arbitrary workpiece to be machined by an arbitrary machine tool, a cleaning condition for cleaning, by an arbitrary cleaning device, the inside of a machine by which the workpiece was machined under the machining condition and state information indicating a degree of dirtiness of the inside of the machine before the machining under the machining condition. The device also has a label acquisition unit that acquires, as label data, state information about the inside of the machine after machining under the machining condition and cleaning under the cleaning condition included in the input data, and a learning unit that executes supervised learning using the input data and the label data, so as to generate a learned model.
