摘要(中)	本論文主要是針對快速塑性成型（Quick Plastic Forming, QPF）之製程精度進行探討。我們透過將製程的“可控變因”固定後，再取足量方形試片，搭配設計過的量測夾具進行測量，重複量測後再將數據計算整理並相互比較得出結論，希望能夠藉此定義出QPF製程之尺寸精度，使QPF製程在更多領域或面向上的使用率能有所提升。 研究結果顯示QPF製程之尺寸精度受設計尺寸大小所影響，國際公差等級大約是落在IT7~10間，這樣的等級並不比現行的許多主流製程差，故希望之後也能再提出針對更多不同設計尺寸量測計算後得出之IT值，使QPF製程之尺寸精度被更為完整的定義。
摘要(英)	This paper focuses on the process accuracy of Quick Plastic Forming (QPF). We fix the controllable variables of the manufacturing process and then take a sufficient number of rectangular box test pieces to measure with the designed fixture. After repeated measurements, the data is calculated and compared with each other to draw a conclusion. It is hoped that the dimensional accuracy of the QPF process can be defined so that the utilization rate of the QPF process in more fields can be improved. The results show that the dimensional accuracy of QPF process is affected by the design size. The international tolerance grade falls between IT7~10. This grade is even better than many current mainstream processes. Therefore, we hope that the IT grade obtained for more different design sizes can be proposed later, so that the dimensional accuracy of QPF process can be more completely defined.
