Abstract
In our previous studies, numerical simulations and experiments were carried out to understand the mechanism of asymmetric spinning for square cone shape. However, the geometry of the products does not coincide well with the geometry in theory. Therefore, in this study, the relationship between the roller and the product is analyzed and a modified roller path is deduced through geometric approach. The result shows the geometry has improved a lot. The relative error of the wall straightness λ drops from 15.9 to 4.1% after modifying. The modified roller path does not have much effect on the wall angle and the wall thickness.
