Finite Element Analysis for Critical Components of Ultra-precision Grinding Machine Tool

The ensemble static stiffness of machine tool is its ability to maintain smooth working condition and resist a variety of loads. As the dispensable part of ensemble static stiffness, critical components stiffness plays a significant role in the performance of the ultra-precision grinding machine tool. In this paper, a three-axis CNC grinding machine tool for the ultra-precision mirror surface grinding of advanced materials such as ceramics and other hard and brittle materials has been designed. And the stiffness and modal parameters of the grinding machine tool are discussed using finite element software. The results are presented and discussed thoroughly. This in turn can help to revise design defects and reduce research and develop costs.
