1. A display device of a machining path for a servo control device configured to control an electric motor that drives axes of a machine tool or an industrial machine, the display device comprising:
a data acquisition unit that acquires time-series data of a position of a driven body or an electric motor on each axis of the machine tool or the industrial machine;
a path calculation unit that calculates a machining path from the time-series data of the position of the driven body or the electric motor on each of the axes which is acquired by the data acquisition unit;
a path comparison unit that, from a result calculated by the path calculation unit, sets a reference plane for a height of the machining path and compares heights of adjacent machining paths from the reference plane; and
a display unit that displays a location where a height difference equal to or greater than a set threshold value occurs on the adjacent machining paths.
