Abstract
Flow forming is a process that uses rollers to form material over a rotating mandrel using principles of drawing/extrusion and rolling. The main focus of this thesis is to develop techniques for capturing, and interpreting process information during a flow forming process and determining material response to the process overall. An analytic solution to the instantaneous upper-bound contact area of the forming tool has been developed. Micro-indentation hardness testing has been used to map the strain to the work piece for a series of reduction levels on 1020 steel using both Berkovich and Vickers-type geometries. Variations in the strain field in experimental work pieces are reported for increasing reductions. Implications on process parameters and the stability of the flow forming process are discussed.
