I have done quite a lot of maintenance work on various industrial
machines. I can't think of even one machine I have worked on that had a
UPS fitted. I have seen a few with line conditioning circuitry where
they have particularly noisy supply. If power cuts are a regular
occurrence I suppose a UPS may be of some benefit but it would have to
be big enough to run the whole machine, which is likely to be very
expensive.
Linux is pretty tolerant to being powered off without warning and it is
very rare to get any form of filesystem corruption from doing so. All of
my machines have the computer buried inside and when I am done I simply
turn the whole machine off. I've never seen any problems with doing this.

I have completed a working concept of the controller, as in, I had it up and
running and actually cut some parts.
My question is, *should* a controller such as this have an uninterruptible
power supply? If so, what parts of the machine are normally served by a UPS?
