Abstract: To improve the design efficiency and the overall performance of cartridge manifold block,a general structure for CAD system was presented based on the design procedure analysis.For the surface layout problem,a backtracking algorithm based on engineering rules was put forward,by which efficient and correct layout results could be achieved with library features on parameter configuration|for the holes routing problem,a multi-hole routing approach was proposed based on the cooperative co-evolutionary ant colony algorithm.Thus the optimal strategies of holes connecting order were given and all inner holes were optimally connected.A cartridge manifold block CAD system was developed under SolidWorks software,with which the application case of a hydraulic press's ejection cylinder part was used to demonstrate the feasibility of proposed system.

Key words: cartridge manifold block, computer aided design system, layout and holes routing, optimal design
