Perfect circle continuous fly cutting method

The invention relates to the technical field of laser cutting, in particular to a perfect circle continuous fly cutting method. The perfect circle continuous fly cutting method comprises the following steps that firstly, all pixels to be cut are judged so as to screen out all perfect circles; secondly, the screened perfect circles are ordered, if a nesting relationship exists among the perfect circles, the perfect circles on an inner layer are ordered firstly, and then the perfect circles on an outer layer are ordered; thirdly, the two adjacent ordered perfect circles are connected through a cutting line segment, and the cutting line segment is made to be tangent to the two connected perfect circles; and finally, all the perfect circles and all the cutting line segments are connected into a complete cutting line, and the direction of each cutting line segment and the rotating direction of each perfect circle are determined to form a cutting route. Therefore, only one complete cutting route needs to be planned
