Claims (1)

[Scope of utility model registration request] The actual machining is performed using an NC automatic programming device that is equipped with a graphic display function, character and coordinate input means, and also has a function to calculate the machining time when converting the graphic drawn on the computer graphic display device into NC data. By inputting the completed NC data and the actual machining time, the machining time calculation coefficient is automatically updated, and the next time the NC data is generated, the machining time is calculated with higher accuracy. NC automatic programming device.
