Tribological measures for controlling material flow in sheet-bulk metal forming
Production Engineering, 2016Sheet-bulk metal forming (SBMF) is characterized by successive and/or simultaneous occurrence of quite different load conditions regarding stress and strain states. These conditions significantly influence the material flow and thus the geometrical accuracy of the components. To improve the product quality a control of the material flow is required. An

Experimental and Simulative Investigations of Tribology in Sheet-Bulk Metal Forming
Key Engineering Materials, 2015Friction has a considerable influence in metal forming both in economic and technical terms. This is especially true for sheet-bulk metal forming (SBMF). The contact pressure that occurs here can be low making Coulomb’s friction law advisable, but also very high so that Tresca’s friction law is preferable. By means of an elasto-plastic half-space model

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.

Incremental Sheet-Bulk Metal Forming by Application of Thermal-Controlled Grading Mechanisms
2020The industrial manufacturing of functional components featuring a load-adapted shape primarily occurs by cutting or joining processes. These processes lead to inferior material efficiency and mechanical properties. The technology of incremental sheet-bulk metal forming (iSBMF) avoids these disadvantages but presents challenges towards a controllable ...

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.

Control of sheet-bulk metal forming processes using tailored tribological Systems
2019The industry is faced with a lot of requirements exemplary regarding a shortening of the process chains, a high functional integration or ecological aspects. Conventional sheet- and bulk forming operations are limited while facing such requirments. One method to meet the existing challenges is the combination of both process classes using sheet-bulk ...
