Abstract:
The prediction of dynamics of a machining center spindle is studied, and the receptance coupling subsystem algorithm(RCSA)is adopted to model the machining system. In the model of the machining system, the tool and tool holder are coupled at two single points, and every point has one lateral displacement degree of freedom(DOF). This two-point model of the machining system does not need to consider the rotational degree, and, therefore, it is easy and feasible. The inverse RCSA is studied to obtain the displacement receptance of the end of the holder. It can solve the issue that the structure of the holder is complicated, not easy to model exactly and the space is narrow, and it is not easy to carry out a hammer testing. And then a case study is carried out, and three tools with the lengths of 245, 147 and 168 mm are coupled with the same holder. The results show that the inverse RCSA can exactly predict the displacement receptance of the holder. The method can be applied to predict the displacement receptance of the tool point with different lengths coupled with a complicated structural tool holder.
