Hi from Norfolk

Another difference is that a in a router the cutter makes all moves while in a mill the work is moved, principally in the horizontal plane. There are of course many exceptions. Spindle speeds are usually higher in the router.

Of course! I'm working on my new router design that has a fixed gantry and moving bed so forgot about that one completely!

Russell, OT slightly, but would it be fair to say that spindle speed (used) would be determined by the material being worked?

I did used to own a mill before I sold all my gear when I moved to the USA thinking I wasn't coming back.

So my limited experience with that would say it does matter.

Yes, that blurs the distinction even more.

Of course. In general the materials routers are used for are softer than those mills are used for. Note, I did say in general:-)
