ABSTRACT:
The Institute for Control Engineering of Machine Tools and
Manufacturing Units (ISW) has researched a continuous concept for a
redundant, failure tolerant numerical control system. This research
project accommodates the raising demands for reliability of machines
in as well as for the increasing adoption of numerical controls in
safety critical applications. Reliability means the ability of a
numerical control to provide its specified function during the whole
machining time. This can be achieved using a redundant design and will
be shown by a demonstrator. This demonstrator, which is based on Linux
with rt-preempt as well as SERCOS III is introduced in this
contribution.
