Provided is a display device (10) which is connected to a numerical controller device (23) and displays operation setting information (23a) of a main shaft which is set by the numerical controller device (23) and operation state information (20a) which represents the operation state of a machine tool (20), said display device (10) comprising: an operation setting acquisition unit (11) which acquires the operation setting information (23a) which is outputted from the numerical controller device (23); an operation state acquisition unit (12) which acquires the operation state information (20a) which is outputted from the machine tool (20); a setting change detection unit (13) which detects a change of the operation setting information (23a) which is acquired with the operation setting acquisition unit (11); and a display unit (14) which, with the change of the operation setting information (23a) which is detected with the setting change detection unit (13) as a trigger, displays, in association with the operation state information (20a) which is acquired with the operation state acquisition unit (12), the operation setting information (23a) which is acquired with the operation setting acquisition unit (11). The operation setting information (23a) includes information which shows the reference rotational speed of the main shaft, and a variation parameter for causing the rotational speed of the main shaft to vary, centered upon the reference rotational speed. |
