Claim:
1. A numerical controller, comprising: a numerical controlling part which controls at least one drive axis of a machine tool; a position data obtaining part which obtains position data of the drive axis and a representative point of a tool of the machine tool; a physical data obtaining part which obtains physical data of the drive axis and the representative point of the tool; a movement distance calculating part which calculates movement distance of the drive axis and the representative point of the tool based on the position data; a data converting part which converts the physical data obtained by the physical data obtaining part, which is time axis-based data, into movement distance-based data, a distance-based data storing part which stores the movement distance-based data; and a displaying part which displays the movement distance-based data, wherein the displaying part further displays at least one past movement distance-based data in a processing condition, which is stored in the distance-based data storing part, on the movement distance-based data in a processing condition different from the processing condition of the past movement distance-based data so that the past movement distance-based data and the movement distance-based data are overlapped with each other, and wherein the movement distance calculating part enlarges or reduces the movement distance of the movement distance-based data corresponding to a movement distance of the past movement distance-based data, and the displaying part displays the movement distance-based data based on the enlarged or reduced movement distance.
