Institut für Integrierte Produktion Hannover
IPH - Institute for Integrated Production Hannover ( IPH also Hannover) is a nonprofit research and consulting service provider for production technology based in the Science Park Marienwerderstraße in Hanover. The institute was founded in 1988 as an offshoot from the Leibniz University of Hannover out of Hans Kurt Tönshoff, Eckart Doege and Hans -Peter Wiendahl.

- 2.2 Production Automation
- 2.3 logistics
Organization
The IPH is organized into three areas: logistics, manufacturing automation and process technology. Interdisciplinary issues (eg XXL products ) are processed across divisions. The Institute is led by three managing partners and a coordinating manager. As a nonprofit corporation, the institute funded by public research funding and industry consultation.
Managing partners
- Bernd -Arno Behrens ( Director of the Institute of Metal Forming and Metal Forming the Leibniz University of Hannover)
- Peter Nyhuis (Head of the Institute of Production Systems and Logistics at the Leibniz University of Hannover)
- Ludger Overmeyer (Head of the Institute of Transport and Automation Technology at the Leibniz University of Hannover)
Coordinating Director
- Georg Ullmann
Work focuses on
Research and development, consulting and training are the three focal points of the IPH. The aim of the institute is to link the production engineering science and manufacturing companies. This is to promote knowledge transfer between science and industry are possible.
The IPH deals with various aspects of production technology:
- Process
- Production Automation
- Logistics
- XXL products
Process
In the process, IPH has been involved since 2000 in the Collaborative Research Center 489 (SFB 489 ). This is funded by the German Research Foundation (DFG) and deals with the " process chain for manufacturing precision-forged high-performance components ." The term precision forging is used in two ways: On the one hand, making it the gratlose forging meant. Alternatively, is spoken by the ( gratbehafteten ) forging when the forgings achieve an accuracy of 7 IT to IT 9. Recent developments have shown the possibility of flashless forging of complicated components, such as crankshafts. For flashless forging of crankshafts suitable preform procedures are required. At IPH in particular the multi-directional forging and the cross wedge rolling are considered here.
The cross-wedge rolling is also subject of research in the design of a process chain for the semi- warm forging. Together with the stretching rollers, the temperature influence is examined for the process and part quality. Another aspect in the process chain is the wear of the forging tools. Here an attempt is made to reduce the wear of the DLC coatings.
In the area of hydroforming IPH investigated materials and material combinations. One example is the internal high pressure forming of titanium. In future, the forming of so-called "tailored hybrid tubes" ( material combinations of steel and aluminum) should be explored.
A novel forming processes, which is being developed at the IPH, the hybrid forging. It combines the forming and joining of solid and sheet metal elements in a single process.
A further development of IPH is a module for fully automated stud welding with tip ignition for integration in sheet metal forming tools. In the field of sheet metal forming also the effectiveness of Blechumformanlagen research is being conducted to increase.

Production Automation
In the field of production automation, the IPH busy with methods of artificial intelligence, distributed systems, and the use of wireless communication in production.
Since the beginning of the new millennium, the IPH research on the use of methods of artificial intelligence in the production technology. One focus of the work is the performance-and economy -oriented planning of assembly systems with linked data mining. Recent research concerned with the positioning of cooling channels in injection molding tools, the design of preform geometries for forging processes and self- control of automated guided vehicle systems ( FTS).
Distributed systems are also subject of research at the IPH. An example is the electronic tool book, which was developed within a BMBF-funded research project. Result of a DFG project is an intelligent cutting grinding tool. The distributed system consists of piezoelectric sensors for sensing vibrations of the tool, a measuring system for signal processing and amplification and a radio module for transmitting the measurement signal to a computer.
In the area of wireless communication IPH investigated the use of various wireless communication technologies. The use of printed antennas using RFID chips to pharmaceutical packaging to protect against counterfeit products was the subject of the research project EZ Pharm. The ZigBee technology enables data transfer from a abrasive cutting blade during the machining process. In recent research, the IPH busy with optical communication. On the basis of visible light, a position determining system for industrial trucks and an identification method for logistic applications are developed.

Logistics
Research focus in the field of logistics, the design and management of economically and environmentally efficient production networks. An example of the research on production networks is that of the German Research Foundation (DFG ) funded project "Synchronization of logistic responsiveness ". The project has been demonstrated through a simulation study, that affect structural interactions within production networks, the dynamic behavior and thus also the logistical achievement strong.
A method for the economic and organizational planning and evaluation of adaptability in supply chains is developed in the BMBF joint project ISI -WALK. It should allow, for example, determination of the correct conversion timing.
In various research, the IPH busy with in-plant production logistics. In the Collaborative Research Center 489 (SFB 489 ), a method was developed to take into account the amount of state Massivumformwerkzeugen in the lot size determination for forgings can. As a result, unnecessary set-up procedures and additional capital commitment costs are avoided in forging company.
A development of IPH, which was implemented in the everyday operations, the performance measurement system for procurement, production and distribution, which in the BMBF project - was developed " LogiBEST logistics benchmarking for manufacturing companies ." Based on this performance measurement system, the VDI guideline 4400 was developed.
