Lightweight joining of polymer and polymer-metal sheets by sheet-bulk forming
Journal of Cleaner Production, 2017Abstract This paper presents an environmentally friendly joining process based on sheet-bulk plastic deformation to connect two polymer (or a polymer and a metal) sheets perpendicular to one another. The methodology draws from material characterization and finite element modelling, using an extension of the flow formulation to pressure-sensitive ...

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

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

Mechanism-Based Modelling of Wear in Sheet-Bulk Metal Forming
2020Friction characteristics and wear of sheet-bulk metal forming tools featuring microstructured surfaces are simulated on the mesoscale. Computational homogenisation is used for surface cut-outs on which the structures are geometrically resolved and where friction laws model lower scale roughness. Two approaches are presented for the modelling of wear. A

Holistic dimensional measurement of sheet-bulk metal formed parts
Optical Metrology and Inspection for Industrial Applications V, 2018Due to recent developments in sheet-bulk metal forming processes, holistic measuring systems are required which provide reliable results for the measurement of all relevant formed part features. The presented multi scale multisensor approach, which combines several fringe projection sensors of different measuring resolutions and ranges, accomplishes ...

Novel Five-Axis Forming Press for the Incremental Sheet-Bulk Metal Forming
Key Engineering Materials, 2013The incremental procedure of sheet-bulk metal forming was classified into two different forming sequences, the discrete and the continuous. Based on these two groups, a movement matrix was developed, which captures required kinematic motions to manufacture a variety of functional components.

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).

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.
