Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: A machine learning apparatus learns a setting value in a machining program of a machine tool configured to machine an impeller. The machine learning apparatus includes a state observation unit configured to acquire the thermal displacement amount during a period of machining a workpiece, as a state variable, and a determination data acquisition unit configured to receive the imbalance amount in the impeller after machining as determination data. The machine learning apparatus includes a learning unit configured to learn the setting value in the machining program on the basis of output from the state observation unit and output from the determination data acquisition unit.
