In electromagnetic forming of thin sheet metal, the die is located within the effective range of the electromagnetic wave. Correspondingly, a current is induced not only in the sheet metal, but also in the die. Like the current in the workpiece, also

In electromagnetic embossing, the interaction of the magnetic field and the induced current density results in body forces that enable the replication of optical microstructures into thin sheet metals. However, as the sheet metal is completely penetr

Additionally to the achievable tight geometrical tolerances, rotary swaging can influence intrinsic material properties by work hardening and residual stresses generation. Although residual stresses should be usually avoided, they can be used on purp

Diamond milling allows for the flexible production of optical and high precision parts, but suffers from poor setup and production speeds. This paper presents recent advances that aim towards achieving high performance (HPC) and high speed cutting (H

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

Rotary swaging reduces the cross section of bars and tubes and usually acts as a cold forming technology. The induced work hardening leads to products with high ultimate tensile strength and low ductility. In contrast, hot forming processes result in

With impulse forming technologies like electrohydraulic and electromagnetic forming, the punch in a stamping process is replaced by an impulse that acts in a short period and provides high strain rates of over 1000 s-1. Beneath the advantages which a
