PROBLEM TO BE SOLVED: To associate track error with a direction of travel to effectively perform a servo adjustment.SOLUTION: A tool track display device (20) comprises: a positional information acquisition unit (21) which acquires at least one piece of positional information of a driving shaft from a numerical control device (16) and at least one position sensor (11-15) provided at the driving shaft; a tool coordinate calculation unit (22) which calculates a coordinate value of a tool (5) on the basis of the at least one piece of positional information of the driving shaft and machine configuration information of a machine tool (1); a display attribute change unit (23) which changes a display attribute of the tool track according to a travel direction of the tool; and a display unit (24) which displays the tool track on the basis of the coordinate value of the tool calculated by the tool coordinate calculation unit, and the display attribute changed by the display attribute change unit. |
