High-feed milling of tailored surfaces for sheet-bulk metal forming tools
Production Engineering, 2014The increasingly investigated and applied production process sheet-bulk metal forming (SBMF) has novel requirements for the forming tools, e.g., the need of an adaptive material flow at different areas of the tool for an adequate form filling. One new method to realize different, defined tribological conditions are tailored surfaces (TS).

Amorphous Carbon Coatings for Sheet-Bulk Metal Forming Tools
2020Sheet-bulk metal forming processes are commonly characterized by temporally and locally varying stress conditions, likely to affect material flow during forming and therefore the geometrical accuracy of formed parts. Local modifications of friction conditions can contribute to control the flow of material and simultaneously to reduce process forces and

Maturity Model for the Development of New Forming Processes Applied to the Sheet-Bulk Metal Forming
Key Engineering Materials, 2012Forming processes are characterized by high cost-effectiveness due to high material utilization and short forming process time. Therefore the development of new forming processes aims for overcoming the current process limitations to produce function extended components with a wider range of application and lower manufacturing costs.

Sheet-bulk metal forming of functional components from coil
2022Die Blechmassivumformung als Anwendung von Massivumformverfahren auf Blech vereint die Vorteile der Blech- und Massivumformung. Aus flächigen Halbzeugen werden dünnwandige und folglich leichte Bauteile mit integrierten Funktionselementen, wie Verzahnungen oder Zapfen, durch einen dreidimensionalen Stofffluss ausgeformt.

Holistic Measurement in the Sheet-Bulk Metal Forming Process with Fringe Projection
Key Engineering Materials, 2012Sheet bulk metal forming is a new forming technology, currently developed by several companies and research institutes. It creates high demands on the inspection of parts and tools, especially in the field of in-situ abrasion detection of the forming tool and its impacts on the work piece.

Joining sheets perpendicular to one other by sheet-bulk metal forming
The International Journal of Advanced Manufacturing Technology, 2016This paper presents a variant of the traditional ‘mortise-and-tenon’ joint, which has been used for thousands of years by carpenters and blacksmiths to connect wood or metal parts. The new proposed joint is utilized to fix longitudinally in position two metal sheets (or plates) perpendicular to one other by sheet-bulk metal forming, at room temperature.

Analysis of Horizontal Loads in Sheet-Bulk Metal Forming and Their Consideration in Simulation
2020Complex forming parts that include functional elements can be produced by means of sheet-bulk metal forming within one process step. Adding functional elements to a workpiece design can lead to design asymmetry. As a result, horizontal forces appear during the forming process, leading to horizontal displacements of the press ram.

Forming of lightweight helical gears by means of sheet-bulk metal forming
Materials Research ProceedingsAbstract. A rising demand on resource efficient and highly functional products causes conventional metal forming processes to the reach their limits. For this reason, sheet-bulk metal forming (SBMF) for the production of thin-walled components with various filigree functional elements has been widely investigated in recent years.
