TOOL LOCUS DISPLAY DEVICE INCLUDING DISPLAY UNIT OF LOCUS DATA

摘要

PROBLEM TO BE SOLVED: To easily compare a shape of a locus for a repetitive part.SOLUTION: A tool locus display device (10) includes: a start coordinate storage unit (13) included in a processing program for storing a plurality of coordinate positions of a drive shaft at each execution start time of a plurality of repetitive parts that congruence shapes are repeatedly processed as start coordinate positions; an amount of movement determination unit (14) for determining an amount of movement of the drive shaft from a first start coordinate position to a second start coordinate position of the start coordinate positions; a locus calculation unit (15) for calculating a first actual locus of a tool tip point of a machine tool from the actual position on the basis of the first start coordinate position and the repetitive parts after the amount of movement is added, and calculating a second actual locus of the tool tip point from the actual position on the basis of the second start coordinate position and the repetitive parts; and a display unit (16) for displaying the first actual locus and the second actual locus to be overlapped with each other.
