Piston ring is the important accessory of the engine and turning its contour is the key procedure to ensure the performance of piston ring it has great value in economy and society that we develop the nc machining system for outer circle of piston ring to manufacture the high quality piston ring and to replace the import machine according to piston ring contour data provlded by the cad system ， it can turn the piston ring contour by controlling the displacement of servomechanism which is controlled by the angle of servo motor it uses the theories of velocity closed loop 、 dlsplacement closed loop and feed forward control to improve the control precision of system on the basis of theories of elastic mechanics and mathematics ， the cad system can provide the accurate data required by the nc machine system according to the calculation model and the parameters of piston ring this system integrates the cad cam technology
系統根據活塞環cad系統生成的介面數據，通過伺服電機的轉角位置控制自主研製的高性能微位移進給機構產生給定的位移，以完成活塞環輪廓的仿型加工。系統採用速度、位置閉環控制及前饋控制理論，以提高系統的控制精度。活塞環cad系統以彈性力學和數學方法為基礎，根據常用的計算模型與活塞環參數自動生成數控加工系統所需的精確的介面數據，實現cad / cam一體化。 -
