摘要: 
近年來五軸工具機蓬勃發展,在許多產業如航太產業的零件製造、生醫、模具及特殊零件等加工都陸續使用五軸工具機來生產。
工具機的組成是由主要鑄件搭配傳動元件構成,本研究利用ANSYS載入五軸工具機模型來分析結構靜態剛性,配合實驗來驗證此模擬結果。
在模擬部份,選定工具機固定的行程與位置,繪製實體模型代入分析軟體中進行結構變形的分析;實驗部份,在設定的位置,利用loadcell配合出力元件與量錶進行量測,最後用圖表顯示模擬與實驗的關聯性,近而預估變形的準確度。
模擬得到的結果與實際量測的數據進行比對,所得到的變形量誤差為44.5%,透過修正影響誤差的邊界條件,將誤差值縮小到符合10%以內。

In recent years, the 5-axis machine tools flourish in many industries such as aerospace, biomedical, molds and special parts…etc., such as processing one after another using the 5-axis machine tools to produce.

The composition of the machine tool is by main casting and driven components. This study using ANSYS load 5-axis machine tool model to analyze the structure of the static rigidity, with the experiment to verify the results of this simulation.

For simulation, to choose a fixed travel and position for machine tool, draw a substantive model into the analysis software to analyze the deformation of structure;
For experiment, using loadcell with output components and scale to measurement set position.
Finally, adopting chart to show the correlation of simulation and experimental, then estimate the accuracy of deformation.

To compare the simulation results and the actual measured data, the deformation error is 44.5%. To modify the boundary conditions which affect errors, and reducing the error value less than 10%.
