Introduction to sheet-bulk metal forming
Production Engineering, 2016Sheet-bulk metal forming as a new class of manufacturing processes is one of the possible answers production processes provide to the increasing demands on functional integration into light weight parts made of high strength steel. Research in this field is carried out in several places.

Sheet-Bulk Metal Forming of Preformed Sheet Metal Parts
Key Engineering Materials, 2011Due to ecological and economic challenges there is a rising demand on closely-tolerated complex functional components. Regarding short process chains and improved mechanical properties conventional forming processes are often limited. A promising approach to meet these requirements can be seen in the combination of traditional sheet and bulk metal ...

Machines and Tools for Sheet-Bulk Metal Forming
Key Engineering Materials, 2011The demand on closely-tolerated and complex functional components in the automotive sector, like e.g. synchronizer rings, leads to the development of a new process-class named “sheet-bulk metal forming”. Within this technology bulk metal forming operations are applied on sheet metals. In the following two novel approaches considering machines and tools

Failure by fracture in sheet–bulk metal forming
The Journal of Strain Analysis for Engineering Design, 2016This article investigates the possibility of failure by crack-opening mode III (out-of-plane shearing) in sheet–bulk metal forming processes. The investigation makes use of experimentally and theoretically determined fracture-forming limits of aluminium AA1050-H111 sheets with 1 mm thickness, experimental tests in incremental ploughing with a roll ...

Fatigue Behavior of Sheet-Bulk Metal Formed Components
2020Functional components manufactured by sheet-bulk metal forming will commonly be exposed to cyclic loading during operation. Due to the cold forming during sheet-bulk metal forming, work-hardening occurs and ductile damage is induced in the form of voids in the microstructure. To predict the influence of specific processing parameters on the components’

Preshearing influences on sheet-bulk metal forming of aluminum gear
Journal of Materials Processing Technology, 2020Abstract Shear-cutting methods are more efficient than machining methods for preparing billets from sheet metal. In this study, several shearing methods were applied to prepare semi-finished billets for sheet-bulk metal forming of duplex gears. The influences of shearing features such as fracture, roll over, and grain flow lines on subsequent forming
