Greetings.
I need to know what spindle rate and feed rate to use on a cut I'm about to try.
This is my first try at milling aluminum. I'm on a Taig 2019 which has spindle RPM rates from 1k to 10k. My aluminum is 6061 and is 0.25 thick. I'll be going in 0.08" passes on this first try - I think my machine can handle that.
The perimeter of the contour for the part is about 6 or 7 inches long. My carbide end mill is 1/8" diameter and has 4 flutes that are about 0.75" long.
So now that I've written the G-Code, what F speed should I add and what speed should I set my spindle to?
Thanks, gs
