Abstract: The whole embroidery region is first decomposed into a series of closed loops and organized into a bintree according to the inclusion relationships among loops.The loops are the n linked together in an order conforming to the sequence of bintree traversal.Loops being cut through are connected by longitudinal linking paths,while latitudinal linking paths are generated to fulfil tool paths transit from the optimally choosen exit point of a loop to the entry point of its adjacent loop.Experiments show that the proposed approach is feasible and effective.
