Computer simulation of manufacturing processes:

This technology provides the possibility to calculate and optimise the workpiece and tool
behaviour during a production cycle.

Our simulation models calculate the complete manufacturing process of metallic components.
Starting from the prematerial all required operations, such as forming, heat treatment and
machining cycles can be included. The properties of the workpiece and the behaviour of the
tools are calculated and can be analysed on the computer.

Under consideration of all technical and technological aspects we achieve a non-stop
development process on a virtual prototype. This is a very efficient way to develop and
optimise the product properties and manufacturing technology including case-studies.

          Aim of these analysis is:
                  efficient development of technology
                reduced production costs by minimizing manufacturing defects
                increase of production rates
                shortening of the lead-time
                improved quality of products and manufacturing processes
                reduced costs for tooling
                optimisation of the product cycle

Forming simulation:

On the bases of the software DEFORMTM , realistic simulation models make the
calculation of the most important manufacturing techniques in metal forming possible.
In these models the relevant data for the workpiece, the material, the tooling and the
process are included.
Considering the influence of the environment, the characteristic of the press, the
workpiece-tooling interface, the material flow and the temperature field the production
process is calculated.

We have successfully run several projects in the technologies of cold and hot forming
listed below:
  Sheet and shape rolling
Wire drawing
Deep drawing
Hydraulic forming
Compacting of porous material
Induction heating


Heat Treatment simulation:

In cooperation with partners we have explored further features of DEFORMTM
to develop simulation models for several heat treatment cycles on steels
and non-ferrous alloys.

Typical quenching in water, oil, air and furnace can be analysed.
In addition different heating methods are included.

The simulation models consider:
  Diffusion type and martensitic phase transformation

Microstructure evolution with recrystallisation and grain growth


Residual stress and distortion

Hardness prediction

Risk of quench cracking



With these newest routines we have models for the analysis of material removal.
The routines are capable of simulating the workpiece and tool behaviour, as well as
the interface between them.
In micro-simulation we calculate:
  Cutting forces
Contact temperatures
Wear rates


Macro-simulation supplies us with information on:
  Machining distortion
Residual stresses

Advantages of the computer simulation:
  Elimination of expensive and time-consuming prototype development

Shortening of "time to market"

Quality improvement through a better understanding of the detailed process

Higher production rates through optimisation

Reduced production costs by eliminating potential operating problems

Higher level of customer confidents

With the computer simulation we get a comprehensive inside into the component and
a detailed understanding of each production step.

By variation of the parameters each process step can be analysed to determine the
process limit and the measures to be taken to ensure the quality.

This knowledge enables you to refine your state of technology and enrich the product
properties in order to precisely meet the requirements.
