PROBLEM TO BE SOLVED: To provide a numerical control device for controlling a five-axis machine tool which finds an optimum permissible correction amount. SOLUTION: The drawing is a schematic diagram of a display device 70 with an input device included in the numerical control device. A keyboard 73 includes number keys, alphabet keys and the like. A prompt area 74 is displayed for inputting a cumulative relative frequency (%) on a display screen 71. An instruction by which an operator sets what percent of a tool direction command is desired to be sufficiently corrected is assigned to "F5" of function keys 72. A value inputted using the number key of the keyboard 73 is displayed on the prompt area 74, and the value is set by pressing the "F5". An instruction for outputting frequency distribution data to an external device (not shown) is assigned to "F6" of the function keys 72, and the frequency distribution data are transmitted to the external device by pressing the "F6".
