Well this is the Walter Machining Calculator output.

And this is what a 6-1/2" long cut at 3/4" wide and .050" deep looks like in 1018 steel at 3500rpm and 60 inches per minute:
The chips it made landed a few feet away from the machine. Not heavy, but hot and fairly sharp. I couldn't actually find any on the machine!
You can hear the spindle work when it enters the cut and unload as it exits.
This is what the inserts look like, just some of the rust from the stock on them. I'm certain I could get at least 30-40 minutes of cut time per edge under those conditions, at a minimum.

The finish is shiny but probably about a 32-40Ra (microinch). It could be smoother at a lower feed rate, but probably wouldn't be as "shiny" from the heat of the process.

Any questions?
