Machine learning device and machine learning method for learning failure prediction of main shaft or motor driving main shaft, and failure prediction device and failure prediction system provided with machine learning device
A machine learning device and a machine learning method capable of detecting signs of a failure before a spindle of a machine tool or a motor driving the spindle breaks down, and a failure prediction device including the machine learning device and A failure prediction system is provided. A machine learning device 5 that learns a failure prediction of a spindle 212 of a machine tool 2 or a motor 214 that drives the spindle, and detects output data of the motor control device 3 that controls the motor and a state of the motor A state observation unit 52 for observing a state variable including at least one of output data of the detector 11 and output data of the measuring device 12 that measures a state of the main shaft or the motor, and a failure of the main shaft or the motor Learning the failure prediction of the spindle or the motor according to a determination data acquisition unit 51 for acquiring determination data for determining the presence or absence of a failure or the degree of failure, and a data set created based on a combination of the state variable and the determination data Learning unit 53.
