摘要
为了解决工业生产中活塞立体靠模的制造难题,针对传统磨削工艺,开发了活塞立体靠模数控车削加工方法。阐述了车削立体靠模的成形机理,提出了一种基于频谱分析的前馈控制算法,并实际应用于控制系统之中。实际加工结果表明,加工精度得到显著改善,同时,缩短了加工时间,降低了生产成本。该方法为活塞立体靠模的工业生产提供了一条新途径。
In order to machine master piston for industry manufacturing, a newly developed numerical controlled turning system was presented, comparing with the traditional grinding method. Its forming process and operation principles were described, a feed forward controller based on spectrum analysis was designed and used in the control system. Finally, the master piston is machined, the experimental results indicate that the cutting accuracy is greatly improved, process time and production cost are greatly reduced. A new way to machine master piston for industry manufacturing is provided.
