摘要：In this work, Single Point Incremental Forming (SPIF), a state of art technique, was carried out on Aluminum AA 6061 alloy sheets and its forming limit was determined experimentally. The straight groove and cupping tests were carried using ball ended tool in CNC vertical milling machine. In order to investigate the effects step depth and depth of grove on formability, the straight groove and cupping tests were conducted. Straight groves were performed along the rolling and transverse directions. The sum of major strain and minor strain as a measure of formability was measured. The forming limit diagrams (FLD) for straight groove and cupping tests were plotted. Moreover the effect of anisotropy of SPIF in rolling and transverse directions was confirmed through the straight groove test. It is also found that the formability decreases as the step depth increases during the SPIF.
