The target of the project is the development of a new
generation of Active Magnetic Bearing (AMB) motor spindles
built with permanent 50kW magnet motor, 50,000 r.p.m. and
AMB motor spindles are especially used for High Speed
Cutting (HSC). HSC will make it possible to reduce cutting
forces, loading to the tools, result in greater chip load,
better surface quality, much higher accuracy on the
workpieces and reduced deforming.
In order to make this new HSC process perform better, a
High Frequency Converter for this new synchronous motor,
with a SERCOS digital interface, has to be developed.
To obtain an optimal cutting process, adaptive control of
the machine tool is required. The AMB spindle
controller will provide signals so the machining process
can be adapted and produce an Intelligent Machine Tool.
