Auto-adaptive minimization of transfer vibrations in multi-stage presses

IFUM | Undesirable vibrations can be generated by the transfer systems used for the fully automated component transfer between several subsequent forming processes. For this reason, researchers at IFUM are developing a system that minimizes the vibrations occurring during transport, thus increasing the productivity of the forming systems.

Micro dimples for friction reduction in heavy-duty diesel engines

IFW, ITV | To increase the efficiency of combustion engines, researchers of IFW and ITV are doing research on how to reduce friction losses in engines. For this purpose, they are machining micro dimples in cylinder liners to investigate their friction-reducing properties.

Research

Innovative process combination for substrate bonding of thermally sprayed coatings

IW | Corundum blasting used as a pre-treatment of coating surfaces is more and more replaced by machining processes. Researchers are developing an innovative combination of processes for the form-locked bonding of thermally sprayed coatings.

Research

Extended forming limits through active material guidance

match | Environment-friendly innovation using fibre composites is impeded by tight forming limits combined with a challenging automation process. In this context, the Institute of Assembly Technology (match) is developing a method for automated mass production.

IFA learning factory: specific utilisation of real-time data

IFA | Practical experience: The workshop on production controlling organised by IFA shows the potential of data-based, real-time evaluations and intelligent support systems for an improved production logistics in companies.

Research

“As-built“ scan enables creation of digital twins

IFW | Creating material flow simulations for bottleneck analyses, factory planning or stock analyses requires a lot of initial effort. IFW is currently developing a procedure that scans the production facilities and then creates a digital simulation model in an automated process.

Research

Ultra-fast assembly by consistent kinematics

ITA | To enable the production of larger quantities of smaller chips, ITA is investigating an ultra-fast assembly technology for electronic components. The researchers are using laser technology for the contactless transfer of bare chips onto a substrate.

Research

Automated 3D printing for highly individual production

IPH | By automating process steps, additive manufacturing can be integrated into industrial value chains. The Institut für Integrierte Produktion Hannover (IPH) gGmbH has been designing a process chain linking 3d printers and mounting stations automatically.

Research

Printing hearing aids with customized hardness zones

LZH | Individually shaped earmolds are already commercially available, but do not take into account the varying tissue hardness in the ear canal. In a joint project on multi-material printing, the Laser Zentrum Hannover e.V. works on hearing aids with customized hardness zones.

Research

Process-reliable definition of subsurface properties

IW/IFW | The quality of a component is dependent on its subsurface properties. However, their process-reliable definition can only be reached by component-specific production control. By the use of soft sensors and a learning process model, the production system shall modify process parameters autonomously.

Research

Understanding digitalisation online

IFW | What does digitalisation mean and how can new work tasks be understood? There are many open questions, but employees often find it difficult to match job and continuing education. To find a remedy, researchers from Hannover are presently developing an online-based learning platform.

Research

Lightweight design: thermomechanical precision forging

IFUM | IFUM uses thermomechanical process control to produce thin-walled gear rims. Within the scope of the joint research project “Lightweight Forging”, such gear rims are combined to weight- and efficiency-optimized gear wheels used for gearboxes in cars.

Research

The best of two materials: light and strong at the same time

IPH | Hybrid structures used in automotive lightweight design are composed of different materials as well as of bulk and sheet metal parts. Hybrid compound forging is a method to create a material bond between a steel sheet and a bulk aluminium part already during the forming process.

Research

Drilling and milling: Robot lets chips fly

IFW | Conventional industrial robots are not suitable for use in machining processes. However, most recent research results present mechanisms that increase the positioning accuracy and stiffness of robots, making them usable in metal machining processes. Research at IFW increased the stiffness tenfold.
