1. a track display device (20) shows the three-dimensional track of physical location that is carried out the object (10) of three-dimensional position control by numerical control device (14), and this track display device is characterised in that,Have:

  • Location of instruction data obtaining section (22), it obtains the data of the location of instruction of discrete described object constantly;

    Actual location data obtaining section (24), it obtains the data of the physical location of discrete described object constantly;

    Instruction line segment definition part (28), it defines adjacent 2 instruction line segment (36,40) on the connect hours sequence at the each point that is equivalent to the described location of instruction;

    Error calculating part (30), the shortest length of perpendicular it calculates from each described physical location constantly to the vertical line (38,42) of each described instruction line segment and connect this physical location with in the length of the line segment (37,39) of the nearest location of instruction of this physical location, the short more side of length, as the error of physical location with respect to command path;

    AndShow the error display part (32) of described error and export at least one side of the efferent (34) of described error to the outside.
