PROBLEM TO BE SOLVED: To provide a numerical control device of a machine tool that includes an efficient regular inspection function of components with a use environment of the machine tool and use state thereof taken into consideration.SOLUTION: A numerical control device 10 of a machine tool comprises: amount of inspection reference state record means 101 for setting an amount of inspection reference state, which is a reference for determining whether it is a time to execute an inspection of a component, for each component and storing the amount thereof; integration value counting means 102 for measuring an amount of state to estimate a life of the component for each component, integrating the amount thereof and storing the integrated amount thereof; inspection time notification means 103 for notifying that the inspection of the component is needed when the amount of state integrated by integration value counting means 102 reaches the amount of inspection reference state; inspection result input means 104 for inputting an inspection result of the component; and amount of inspection reference state change means 105 for changing the amount of inspection reference state for determining a time to execute a next-time inspection thereof on the basis of the inspection result input by the inspection result input means 104. |
