Even if using trochoidal (adaptive, i-Machining, etc.) tool paths with constant engagement which take a lower chip load I'd be surprised if the finish wasn't poor because of the high feed rates causing vibrations in the frame and gantry which transfer to the tool.

I know it's not what you want to hear me saying, esp as I suspect with you being located in Cumbria that you might have something to do with this company. But I've built enough machines to know what it takes to cut aluminum properly with a good finish and this machine isn't strong enough IMO. . . . And I'm not even bring rail parallelism and accuracy, etc into the argument which again has a huge impact on finished work.!!
Hi Dean
I put a post up in reply to one of your posts regarding this a few days ago, but I don't know if you have seen it.
I want a CNC router, say 1000 x1000 or preferably half 4x8 ft sheet so that in two steps, I could route/mill a 4x8 foot sheet when needed
If I did want to build one myself with the main purpose of routing aluminium sheets and milling alumium parts, what would your suggestions be for me to build one ? Ie are there any plans out there that you would recommend to base my build on ? I do have access to a manual mill and lathe (Warco ones)
Alternatively, I noted in one of your posts that you also build machines. Would would it cost for you to build me such a fit for purpose machine ?
Many thanks
