| Summary: | 碩士 === 國立臺北科技大學 === 製造科技研究所 === 100 === The paper aims to investigate the aluminum sheet metal (AA1050) forming on the formability and the process limit of circular cup by using single point incremental forming (SPIF) process. The literatures of the previous investigation on high-inclined angle part are mostly in low depth-width ratio, while the paper aims to form a circular cup with a depth-width ratio 1:2 by using multi-stage process to investigate the rounding limit and improve the quality of the cup. In this paper, all experiments were performed on a CNC milling machine in which the experimental sheet metal was appropriately fixed in a special designed clamping fixture mounted on the machine table and the punch tool was installed on the machine spindle. After that, forming operation can be executed by the NC commands generated from the designed tool paths data. The experimental results show that the forming limit can be predicted and the quality of the cup bottom can be improved by using present method.
