PROBLEM TO BE SOLVED: To provide a numerical control device which identifies a stop place and a stop factor of a drive shaft of a machine tool, and can indicate information for shortening a stop time corresponding to the stop factor to an operator.SOLUTION: A numerical control device 100 comprises: a storage part which stores operation situation data, an execution place and stop factor information in relation to their acquisition times; a shortening information storage part 23 which stores the shortening information of a stop time corresponding to the stop factor information; a stop factor shortening information acquisition part 17 which acquires the shortening information of the stop time corresponding to the stop factor information from the shortening information storage part 23 on the basis of the stop factor information which is stored in the storage part; and a display part 21 which displays the execution place and the stop factor information which are stored in the storage part, and the shortening information of the stop time corresponding to the stop factor information which is acquired by the stop factor shortening information acquisition part 17.SELECTED DRAWING: Figure 1 |
