碩士 === 國立虎尾科技大學 === 自動化工程系碩士班 === 106 === It will have some deformation and affect the product sizes on machine center by the static force. This thesis uses CATIA to complete 3D modeling, assemble the design and analyze the data setting. Next step, using the existing Machine Center for the Static stiffness analysis, resulting in an increase in the static rigidity. This thesis utilizes the Functional Principle Method to calculate the Movement Calculation and Power Calculation of the head on the beam’s horizontal movement, vertical up-or-down movement. It turns out that we set the acceleration as 0.1g can meet this machine’s conditions. However, this paper utilizes 0.5g as the conditions of the acceleration. By reinforcing the head, the beam, and the all junctions of the structure. This paper found that the deformation reduced from 90µm to 59µm, and the rigidity increased about 25%. Next, this thesis reduced the deformation of beam by Counterweight. In the end, this thesis got the outcome that the final deformation reduced to about 33μm, and the static stiffness increased to about 63%.
