Flexible spinning with three internal support rollers can allow the economic production of very low-volume or one-off prototypes by removing the need for a mandrel. However, to produce a range of shallow products accurately, it is necessary to position the internal support rollers correctly and to compensate for springback. This paper demonstrates the use of a laser scanner to monitor the current workpiece, position the internal rollers correctly, and compensate for springback. The approach is demonstrated by producing a 316 mm cup with a 50 mm corner radius with a geometric error of just 1.5 mm.
