Learning model construction device, and control information optimization device

A learning model construction device comprising:

• an input data acquisition means that acquires, as input data, control information including a combination of an operation pattern of a drive device of a spindle and parameters related to machining in a machine tool, and temperature information of the spindle prior to performing the machining based on the control information, which is a combination of an operation pattern including at least any of revolution speed of the drive device of the spindle, cutting feedrate, cutting time, and a dwell for which making the drive device of the spindle standby for a designated time, and a parameter including at least any of a time constant of acceleration/deceleration, and a cutting federate override;
• a label acquisition means for acquiring temperature information of the drive device of the spindle after having performed the machining based on the control information as a label;
• and
• a learning model construction means for constructing a learning model for temperature information of the drive device of the spindle after having performed machining based on the control information, by performing supervised learning with a group of the input data and the label as training data.
