Investigation of spin ability to prevent wrinkling and fracture failures in metal spinning
Supervisor: Dr Hui Long

Metal spinning in modern times has been widely used in various industries requiring high precision and high integrity in applications. As one of the near-net shape metal forming processes, modern spinning processes are capable of forming workpiece of thickness from 0.5 mm to 30 mm and diameter of 10 mm to 5000 mm. The design of multiple spinning tool paths is of crucially importance to produce the required geometrical shape and accuracy without material processing failures such as wrinkling and fracture.

This project investigates spin ability of metal spinning processes by testing and modelling material deformation in order to relate spinning mechanics to the mechanism of wrinkling and fracture failures in processing. Finite Element simulation of typical spinning processes will be developed to gain an in-depth understanding of material deformation mechanics. Forming limiting criteria and key factors defining spin ability for wrinkling and fracture failures will be developed by designing experimental tests representing the deformation mechanics in spinning processes. The outcome of this project will provide the forming limiting criteria of spinning processes to design spinning processes without material processing failures of wrinkling and fracture.
