Computer Aided Engineering - Application and Programming
Recent rapid progress in the development of information technology has brought about great changes
in the application of computers in design: new working models have emerged, leading to a new
understanding of product development. This is reflected in the digital description of processes.
The two-dimensional design of the geometry has changed to three-dimensional modelling on grounds
of the integrative demands. The geometric models are changing to virtual product models; with the
aid of all these, the tasks of the process chains can be supported.
The use of management systems
is of ever-increasing importance for the designing of processes and the administrative tasks and
memory functions. This virtuality has to be interpreted as a triad: it means a complete digital
procedure, in the sense of virtual companies it expresses the distributed procedure by means of
networks and makes it clear that multimedia techniques and virtual reality are applied. We can
safely say that in future all complex products will be anticipated in a virtual way.
This lecture will summarise the necessary techniques and methods.
