Controlled die-less metal spinning with optional asymmetry

Metal spinning is used to manufacture high-value parts to near-net shape in low volumes and with high precision. However, until now, each new part needs a dedicated mandrel driving cost and delay which is increased by the time required for tool-path design. Further, most spinning equipment is limited to axially symmetric parts.

A University of Cambridge research team, in partnership with supply chain stakeholders, has delivered a step change in the productivity of metal spinning. Their new process demonstrates the ability to produce spun parts without mandrels, with a significant reduction in set-up and switch-over time, resulting in more rapid introduction of new products.  It also allows a wider range of product geometries including re-entrant shapes, closed-loop feedback control based on product geometry and tool-force sensing, and production of asymmetric parts.
