A Study on the Snake Motion of a Machine Tool Cross-Head Moving with Dry Friction on LM Guides
LM 가이드 상에서 건마찰 접촉을 하면서 운동하는 Cross Head의 사행동에 관한 연구
Abstract
This paper reviews the concepts of the snake motion which can be often observed on the bodies moving along guide rails. A simple modelling is proposed in order to analyze the snake motion of the cross head assembly and force and moment equilibrium equations are established. It is determined the critical conditions at which snake motion just brings about. Some possible methods to reduce or prevent snake motion are discussed in detail.
