Tool path display device provided with a display portion of the locus data

摘要

The tool trajectory display device (10) includes: a start point coordinate storing unit (13) that stores a plurality of coordinate positions of a drive shaft as start point coordinate positions; a movement amount determining unit (14) that determines a movement amount of the drive shaft from a first start point coordinate position to a second start point coordinate position; a trajectory calculation unit (15) that calculates a first actual trajectory of a tool tip point of the machine tool from the actual position based on the first start point coordinate position after adding the movement amount and the repetition portion, and that calculates a second actual trajectory of the tool tip point from the actual position based on the second start point coordinate position and the repetition portion; and a display unit (16) that superimposedly displays the first and the second actual trajectories.
