Shear spinning is usually performed while the flange of the workpiece is kept in flat and perpendicular to the rotational axis. This paper proposes a spinning method using force control with a coordinate transformation for shaping products which have inclined processing part, and evaluate the basic feature of the process by forming of obliquely truncated cone shells. The thrust force along a flange of a product is maintained constant value using impedance control method, while the position of the roller is constrained on the inclined flange plane. This process is also able to apply for a non-axisymmetric die, and neither three-dimensional data of a die nor tool trajectory data is needed. The effectiveness of the proposed method is experimentally verified in forming of pure aluminum sheets of 150mm diameter and 1mm thickness. In comparison with the known process which can make similar shape proposed by authors, this method can form desired shapes with higher profile accuracy.
