David, just up the road from me is an aerospace company, they have something like 25 CNC mills, 3 of which are the latest 5 axis DMG at £5000,000 a pop, and 3 CNC lathes.
None of their guys can use a manual machine.
It's just a different learing curve.
Their big Haas mill with 2 metre bed is programmed to run flat out all day, 18,000 rev spindle and all moves are G00 rapid moves. The only variables is depth of cut and step over.
Possibly years ago you had a transition where manual guys moved to CNC but now it's all about being trained to use CNC.
Top end program's run what is known as HSM, high speed machining, tooling is chosen for this.
Ask Ketan, when he was looking at some inserted tooling the tooling people were quoting totally insane feed rates. So both of us went up the road and spoke to the guy one one of the 5 axis machine [ who incidentally program's his own two machines and he's not a fool, I'd like to see some guys program some of the jobs they do ] and asked him if they could use this tooling?
The answer was no, not on the current machines they are running and to get close to what the tooling people were saying they would have to fit the upgraded spindle from 25Kw at 24,000 revs to 35Kw at 42,000 revs.
So tooling at the moment is better designed than most machines that run it. Not much good giving this to a manual miller then is it ?
