MACHINE LEARNING APPARATUS AND METHOD FOR OPTIMIZING SMOOTHNESS OF FEED OF FEED AXIS OF MACHINE AND MOTOR CONTROL APPARATUS INCLUDING MACHINE LEARNING APPARATUS

摘要

A machine learning apparatus includes: a state observation unit that observes a state variable composed of at least one of data relating to the number of errors that is an error between a position command relative to a rotor of a motor which is drive-controlled by the motor control apparatus and an actual position of a feed mechanism unit, an operation program of the motor control apparatus, any command of the position command, a speed command, or a current command in the motor control apparatus, data relating to a workpiece machining condition in a machine tool including the motor control apparatus, and data relating to a state of the machine tool including the motor control apparatus; and a learning unit that learns a condition associated with the number of corrections used to correct the above-mentioned command in accordance with a training data set constituted by the state variable.
