摘　　要：发动机气缸是发动机的关键部件,气缸孔的加工质量直接决定了发动机的各项性能。为了解决气缸孔镗削加工成腰鼓状的问题,设计了一种推、拉镗相结合的新型推拉镗刀杆,并采用自适应控制技术进行刀具磨损补偿,同时对加工圆柱度误差也进行了补偿。实践证明,采用该加工方法能有效控制误差,提高精镗精度。Engine cylinders is a key part of engine. The machining quality of cylinders infects the characters of engine directly. In order to solve the shape of drum and finish machining during fine-boring cylinders, the paper designs a new push/pull boring bar combined push boring and pull boring. The paper uses the technology of cutter compensation and adaptive control, and cylindricity error is also been compensated. Experiments indicate that push/pull boring bar can control the errors effectively, the machining p...
