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 solve the manufacturing problem of piston three-dimensional model in industrial production, aiming at the traditional grinding technology, a three-dimensional piston-driven three-dimensional numerical control turning method was developed. The shaping mechanism of turning three-dimensional model is expounded. A feedforward control algorithm based on spectrum analysis is proposed and applied to the control system. The actual processing results show that the processing accuracy has been significantly improved at the same time, shortening the processing time and reduce production costs. The method provides a new way for the industrial production of the piston three-dimensional model.
