Pipe cutting machine cutting path obstacle avoidance method, computer readable storage medium and pipe cutting machine

The invention provides a cutting path obstacle avoidance method for a pipe cutting machine, the pipe cutting machine comprises a cutting head and a chuck, and the distance between the cutting head and the chuck in the axis direction of a pipe is L. The method is characterized in that the end, extending out of the chuck, of the pipe is defined as an initial end, and the end, away from the initial end, of a to-be-cut hole is defined as a far end; the method comprises the following steps: acquiring a cutting path of each hole, and calculating the length of each hole along the axis direction; according to the length of each hole in the axial direction, all over-long holes are recognized, the starting point position of each over-long hole is modified, the distance between the starting point position of each over-long hole and the far end of each over-long hole in the axial direction is not larger than L, and the length of each over-long hole in the axial direction is larger than L; and cutting according to the mod
