To provide a numerically-controlled machine tool capable of associating a time chart of an instruction value, a feedback value, and a processing load in a movement instruction, and a processing program, and displaying them on the same screen.

The numerically-controlled machine tool that comprises a feed shaft drive means for driving a feed shaft of the machine tool, a main shaft drive means for rotatably driving a main shaft equipped with a tool, a control means for controlling the feed shaft drive means and the main shaft drive means based on the processing program, and a display means, acquires, in real time, time-series data of an instruction value, an FB value and a processing load in the movement instructed by each movement instruction while processing a workpiece based on the processing program, associates the time chart of the instruction value, the FB value and the processing load, and the processing program, and displays them on the same screen of the display.
