A Displacement Analysis of 2-Dimensional Tool Vibrator
2차원 공구진동기구의 변위 해석
Abstract
In this paper, the theoretical tool displacement and surface roughness are analyzed based on the tool locus of a 2-dimensional tool vibrator. At first, the effects assuming no structural deformation of such variables as frequency, amplitude and phase difference that determine tool loci are simulated. The results show that larger amplitude and/or higher frequency makes better surface. However, a real tool vibrator has the structural deformation, much or less, depending on the excitation frequency. Applying FEM analysis to the deformation of a designed 2D tool vibrator according to the excitation, it has been proved that in this case the displacement is 5
