Expansion of the Fused Filament Fabrication (FFF) Process Through Wire Embedding, Automated Cutting, and Electrical Contacting

open access: yesIEEE Access, 2021
Additive manufacturing is establishing new forms of manufacturing processes to produce functional parts. It is thus seen as a hope for a shift towards decentralised production and the associated positive effects on the environment.

Adiabatic Blanking: Influence of Clearance, Impact Energy, and Velocity on the Blanked Surface

open access: yesJournal of Manufacturing and Materials Processing, 2021
In contrast to other cutting processes, adiabatic blanking typically features high blanking velocities (>3 m/s), which can lead to the formation of adiabatic shear bands in the blanking surface.
