To provide a thrust cutting method and a thrust cutting program creation device preventing vibration without affecting machining efficiency.

A rotary device 1 for the thrust cutting is movably or rotatably set in a machine tool. When setting thrust cutting positions P3, Q3, and R2 pertaining to a plurality of machining lines 11, 12, and 13 in machining outlines 5 and 6 of a work 2 and performing a repeated thrust cutting, the thrust cutting position R2 in the machining line 11 where the rotating direction of the rotary device 1 coincides with the progressing direction of the machining to the work 2 is set to a delayed position to the progressing direction of the machining from the other thrust cutting positions on the segment and the position R2 is thrust-cut after cutting the other thrust cutting positions on the segment.
