Successful market launch: DigiSim – The digital simulator from Müller Weingarten
The digital simulator, known as DigiSim for short, was presented to the trade audience for the first time at EuroBlech last autumn and attracted a great deal of interest. After all, with the digital simulator, Müller Weingarten has developed a tool that can be used to support optimizing the material flow within the press through a virtual approach.The objective is to improve the efficiency of new and existing machines in the most straightforward possible procedure. Even before a machine is built or whilst an existing machine is running, the stroke rate and movement systems of the machine can be optimized. As a result, the digital simulator represents "Virtual Tuning" within PressTuning (Motion Tuning, Control Tuning and Virtual Tuning).
"The advantages of the DigiSim are that with the support of an established system in the automotive and components industries - CATIA V5 - it can ensure that the "designed" part remains consistent from the method and sequence planner through to the die design," says the R&D Director Georg P. Holzinger, explaining the significant benefits. The process results in a simulation of the optimum production process that is tailored to the selected production line and for the specific component. This takes account of all marginal conditions at the same time as achieving the highest possible parts output.
The unique selling point of the "DigiSim" digital simulator involves the offline programming of the associated press.
This means all the parameters established in the simulation can be transferred directly to the press control system.
DigiSim meets customers' needs. Two well known German premium car makers have already purchased the "DigiSim". And now the range of applications for the "DigiSim" is set to be expanded. "In the past, we remained in the SynTec world, but now the design of our digital simulator is so flexible that it can also be used for electronic 3-axis transfer systems and it links the transfer to the control and visualization systems."
For this purpose, the DigiSim is no longer designed for specific machines, but is based on parameters. "This means, in theory, it could also be used for optimizing machines from other manufacturers," continues Holzinger, envisaging new market potential.
