Abstract: To improve the machining efficiency and precision of the ship model surface significantly,the symmetrical machining technology and its implementation mechanism was introduced according to ship model surface’s symmetrical characteristic.The symmetrical machining integrated system for 4-axis ship model surface was put forward,which included the preprocessing module,the CAD module,the CAM module,the post-processing module and the CNC module,and the design principle as well as the key technology on system modules were analyzed.The seamless connection and switched freely between these five modules were realized by adopting the existing CAD/CAM integration technology and the unified database.Based on the above researches,the first set of 4-axis symmetrical machining integrated system for ship model surface in domestic was developed independently,by which the application proved the effectiveness of proposed method.
