This thread got me Googling for similar stuff and I found this:

350 tonne casting made from a 600 tonne pour and machined to within +-0.1mm - "western world's largest steel castings". So we do have the capability in some places as people have said. I know it's not a machine but bloody big for one bit!

That's a man-sized casting!

lol CNC forums!

Yes I know it’s a bit nerdy, but I have been searching around for dxf sample files to use with the new router machine I am having installed this month.

One of the first sample tests we will be making is this T-Rex, to give to some of our customers before Christmas:

What machine out of interest and have you sorted out which software?

I bought a Heiz CNC-Step from Germany at the beginning of the year - the machine was "cheap" the software is by far the largest cost in time and money.

I'm guessing you already frequent www.cnczone.com ?

Our setup will be the best part of £100k by the time its ready next month, and yes the software is very expensive. We will be using SolidWorks files from one of our product designers. For signs and fancy stuff we will be using www.artcampro.com

And yes I have been on that forum as well as a few others.

Yup, the exact two companies I mentioned previously: Sheffield Forgemasters and Davy Markham. Realistically the only two companies left in Britain capable of doing this kind of stuff.

I worked on a few 300+ tonne castings in the past; mill housings and press frames very similar to the one in the report. This involved mostly CAD modelling of someone elses designs for the solidification software analysis.

Here are a few of my own designs for cast offshore nodes for oil rigs. I used to do the conceptual design, right through CAD modelling, F.E. stress analysis and production drawings. These things were welded into the spaceframe or 'jacket' that the rig stands on, and were usually the hard points on the structure by which it was lifted and/or rotated into place on the sea bed. Those stress calcs had to be right...







Great experience to work there for 10 years or so, but I'm more than happy to be in aerospace research now: far cleaner!
