Claims

[Scope of utility model registration request]

A first memory that stores a correction amount set for tool wear, a second memory that stores a set amount of wear per predetermined unit, and a third memory that stores tool cutting information. , a wear amount that counts the cutting information and constantly updates the contents of the third memory, and calculates the current tool wear amount based on the data of the first, second, and third memories read by the tool selection command. A numerical control device comprising a calculation device and a correction device that performs tool wear correction using the wear amount calculated by the wear amount calculation device.
