Dynamic Characteristics Analysis of a 5-Axes Multi-tasking Machine Tool by using F.E.M and Impulse Hammer Test

다기능 5축 복합가공기 램 헤드 모듈의 동특성 분석

This paper describes a case study on dynamic characteristics analysis of a 5-axis multi-tasking machine tool of ram-head typed. Natural frequency and corresponding vibration modes of the machine tool structure were obtained by using both FEM modal analysis and an experimental modal test(impulse hammer test). Both the theoretical and experiment analysis results showed good agreement with each other. Finally, some discussion and review, from the view point of resonance vibration and/or mode coupled chatter, were made based on the analysis results.
