    Abstract: 本文的目的是以精密射出成型製作微飛行器零件,針對不同材料進行機械性質之分析。由於微飛行器各部份零件之功能需求有所不同,利用ASTM 標準,對兩種材料(POM ; PA66)進行磨耗; 拉伸與衝擊試驗,以作為微飛行器各部份零件材料選用之參考。結果顯示POM 之抗拉強度優於PA66 ;衝擊試驗中, POM 之衝擊強度優於PA66 ;磨耗試驗中, POM 之耐磨耗性質略高於PA66 '因此連桿,基座及齒輪選用POM 材料進行製作。本文針對精密射出成型做成型性之探討,並利用成型視窗找出田口法之參數,以田口實驗計劃法,找出影響微飛行器零件收縮之重要參數,並找出最佳化的製程參數。結果顯示,影響收縮最重要之製程參數依序為模具溫度; 射出壓力; 保壓時間,最後是熔膠溫度。三個零件之最佳化製程參數相同,皆為AIBIC3D3 '分別為模其溫度的。c ; :熔膠溫度220 0C ; 射出壓力500b訂以及保壓時間2 秒。
    This investigation fabricates the parts of MAV(Micro Aerial Vehicle) by using precision injection molding.The authors use different polymer materials to do the material testing. The authors base on ASTM standard, focus on two materials (POM, A66) to carry out the wearing testing, tensile testing and impact testing. In the tensile strength testing, the tensile strength ofPOM is better than PA66. In the impact testing, the impact strength of POM is better than PA66. In the wear testing, the wear resistance of POM is better than PA66 slightly. So the linking stickpart, base part and gear part are chosen POM as the injection material. This study uses precision injection molding to fabricate the MAV parts. The authors find out the processing window of POM material, and according to the processing window and then to determine the parameters of Taguchi method setting. The authors will find out the optimum processing parameter. The results show that the most important factor for shrinkage is followed by mold temperature, injection pressure, packing time, and the last one is the injection temperature. The optimal parameter is AIBIC3D3, it is mold temperature of 80�C, injection temperature of 200�C, injection pressure of 500bar and packing time of 2 second.
