Design and modeling of integrated Hall-effect sensor based on-line thickness measurement device for incremental sheet forming processes

The use of Numerical Control and computers in manufacturing has enabled the development of new sheet forming processes. One of these flexible processes is called Incremental Sheet Forming (ISF) in which deformation is localized by the movement of a spherical or flat forming tool. ISF is carried out regularly by a CNC machine tool or by a Robot, which follows a tool-path generated by CAM programs, without the need for costly dies. Despite research progresses in understanding the deformation mechanism in ISF the process still needs a further optimization to guarantee the reliability required for industrial applications.

New Solutions in Online Sheet Thickness Measurements in Incremental Sheet Forming

This work discusses an approved analytical framework of Single Point Incremental Forming (SPIF) of sheet metals, which is capable of modelling the state of stress in the small localised deformation zone in case of corners, flat and rotationally symmetric surfaces. The discussion focuses on the investigation of the sheet thickness prediction in the shell element used in the framework. Novel solutions are introduced in terms of on-line sheet thickness measurement and an adaptive control algorithm in SPIF. Results were experimentally verified for 0.5 mm thick Al 1050 sheets with variable wall angle geometry. Furthermore, a new device for two sided incremental sheet forming is introduced as a recently patented solution in Incremental Sheet Forming (EP2505279).

Novel Incremental Sheet Forming System with Tool-Path Calculation Approach

Incremental Sheet Forming (ISF) is a prosperous forming technique since the end of the 20 th Century. Research projects are still active in this topic with the goal to understand more deeply this flexible process and to reach the full industrialisation of it. These investigations are mainly focusing on the one-side version of ISF, however only the two side variants of this process could reach the ultimate flexibility. This paper gives an overview of the recent results and inventions in the field of ISF processes. A new solution of the Two-Sided ISF processes realisation is given. A new approach to the tool-path calculation is outlined which is based on a recently patented system of the authors.

Re-make of Sheet Metal Parts of End of Life Vehicles - Research on Product Life-Cycle Management

Today it can be accepted as fact that mankind is running out and will soon have shortages of energy, row materials and water. Sustainable development (or more often used sustainability) means to use as little materials, energy and water as possible. Material saving causes energy and water saving as well. Product Life Cycle Management (PLCM) of any kind of product starts when the idea of a product is born and lasts until complete dismissal through steps as detailed design, assembly design, part manufacturing, assembly, testing, diagnostics and operation, advertisement, service, maintenance, etc. Then finally our topics, namely dismantling/ disassembly and dismissal are coming. Dismissal often can be substituted by re-cycling or re-use, or re-make.

Smart connected and interactive production control in a distributed environment

The European research project INT-MANUS embedded in the I*PROMS European network of excellence addresses the increasing demand for flexibility and adaptivity, which is summarised by rapid reconfiguration of complete factories, flexible reaction to new demands as well as related aspects in human computer interaction (HCI), software, and production systems. The projects main goal has been to develop a new technology for the production plants of the future: the Smart Connected Control Platform (SCCP). This platform allows controlling a factory with the help of an open distributed and learning agent platform that integrates machines, robots, and human personnel. It offers an enterprise service bus like concept for dynamic and decentrally controlled production systems, which flexibly connects machines and IT systems like robotic transport systems, terminals, mobile control systems, etc.
