PURPOSE: To totalize the machining results of a specific work and in a specific period by one-touch operation, to display the totalization result on a display device, and to file and output it to external equipment by the numerical controller which controls a machine tool.
CONSTITUTION: A time generation part 9 generates time data. A machining result data gathering part 14 gather machining result data consisting of the name of a machining program and ≥1 time data by specified machining programs. A matching result data gathering part 16 extracts mutually relative machining result data among the machining result data and totalizes the extracted machining result data. A display control part 12 displays the totalization result of the machining result data totalization part 16 on the display device 13. A totalization file generation part 18 files and outputs the totalization result of the machining result data totalization part 16 to the external equipment through a file input/output control part 4.
