During eccentric rotary swaging, the material is severely strained with a high amount of shear stress leading to ultra-fine grained microstructures. The workpiece is fed axially into the swaging head and is formed radially with consecutive forming st

The process investigated in this paper consists of cold rotary swaging of steel bars. In recent work, surface residual stresses were found to be sensitive to process parameters and their fluctuations, leading to variations of residual stresses at dif

Material properties like yield stress and hardness change during forming. Metastable austenitic steels are characterized by an elevated work hardening potential due to strain-induced transformation of austenite into martensite especially by multi-sta

Cold forming processes are very efficient for bulk production. However, the achievable geometries are restricted not only by the process kinematics and tools but also by work hardening. Especially with metastable austenitic steels higher deformation

Infeed rotary swaging is a cold forming production technique to reduce the diameter of axisymmetric components. The forming is achieved discontinuously by a series of radial strokes that are spread over the shell of the part. Due to tolerances within

Infeed rotary swaging is an established incremental cold forming production technique for axisymmetric workpieces. Among others, work hardening as well as near net shape forming are advantages of this production technique. Due to the incremental open

Cold forming initiates a change of the material properties like flow stress and hardness. Due to work hardening and the accompanied loss of formability some intermediate heat treatment may become necessary in multi-stage forming processes. One possib

Rotary swaging is a well established cold forming process e.g. in the automotive industry. In order to modify the material properties by swaging systematically, a new process of swaging with asymmetrical strokes of the forming dies is investigated. T

FE simulation was applied to study the material flow during infeed rotary swaging. The neutral plane according to the process parameters was investigated and compared with experimental results. A single forming stroke was analyzed precisely by using
