Parameter identification for a single-degree-of-freedom system using autoregressive moving average model: Application to cutting system

This paper presents parameter identification for the single-degree-of-freedom (SDOF) system. The proposed method uses an autoregressive moving average (ARMA) model and a bisection method with the free acceleration response of the system to an impact test. The method has been tested on the numerically integrated accelerations from a known SDOF system. The experiment has been conducted on cutting system with an end mill. The validity and advantages of the method are presented. The results show that the proposed method gives parameter identification with good quality for short accelerations using the ARMA model and the bisection method for the SDOF system.
