Abstract：

In single point incremental forming(SPIF),the final thickness of a deformed sheet can be predicted by the sine law,the formability in SPIF can be expressed as the maximum wall angle that a sheet would endure without fracturing. The experimental set-up was designed and the maximum wall angle for aluminum sheet LY12M was investigated by two tests. In the first test,the approximate maximum wall angle by forming the varietal wall angle conical frustum was obtained. In the second test,the conical frustums and obtained the maximum actual wall angles was designed. The maximum actual wall angles for aluminum sheet LY12M was 65°. This method is simple and feasible in predicting the maximum wall angle.
