Abstract


Clothing , footwear , handbags and other enterprises in the fierce market competition and increasing customer demand personalized trend constantly facing new challenges in terms of production technology . Cutting Equipment as an important tool for processing clothing , shoes , purses , etc. , its performance is good or bad determines the level of product quality and the size of the production costs . Domestic small and medium-sized enterprises still remain in the backward state of manually cutting and punching , while imports cropping system , high prices and limited technological transformation of SMEs . Therefore, the development adapted to the small and medium enterprises , multi-layer fabric / leather material with independent intellectual property rights of CNC cutting machine is of great significance to improve the market competitiveness of enterprises and production capacity . By analyzing the status quo of CNC cutting machine at home and abroad , that cutting systems deficiencies , and the corresponding optimization technology Research discusses Finally, this paper studies . For the control object and control functions of the system , on the basis of the working principle of CNC cutting , CNC cutting systems overall program design , based on the PC platform , and leads to a high-performance cutting machine is required to solve the problem . Clipping path optimization problem , we need to consider the outline of the cutting sequence , and each contour point position under the knife , so the tool path attributed to generalized traveling salesman problem . Improved adaptive genetic algorithm with dynamic programming combining two combinatorial optimization method based on genetic algorithm optimization for TSP , and optimize the performance of the algorithm . Problem for artificial selection feedrate exist , that a reasonable choice of the importance and complexity of the feed rate . Through its analysis of the relevant parameters in the the offline speed optimization method based on proposed cutting feed rate the fuzzy optimization control method , and speed optimization system detailed design . Finally, compared with the actual processing of data , and to verify the performance speed fuzzy optimization . Finally, this paper presents the control system design based on the development of motion control card based PC GT CNC cutting machine and motion control systems . In the platform , the path of the proposed optimization method and feed rate optimization methods in the practical application of cutting machine system .
