  • Machine learning device, numerical control device, machine tool, and machine learning method
    Patent number: 10899009
    Abstract: A machine learning device that learns a waiting time for at least one of grasping of a workpiece by a spindle chuck and releasing of the workpiece by a loader chuck during transfer of the workpiece between the spindle chuck—that grasps and sends the workpiece and the loader chuck that grasps and receives the workpiece. The machine learning device includes a state observing unit that observes the waiting time and a FB current from a drive unit that moves the loader chuck as state variables, and a learning unit that learns the waiting time with which a transfer time of the workpiece is shortened, in accordance with a data set created based on the state variables.
