MIRCO ENDMILLS

[cunder]

I will be doing some small pocketing, .010" deep, two .005" passes, in 7075 aluminum. This is on a Roeders machine with a 36,000 rpm spindle. I will be using a .010" dia. Micro 100 2-flute endmill at max RPM. Any idea what feed rate I can get away with?

.0002 chip load will give you about 7.2 ipm.

That should do it.

In 7075 I think you could push it to .001 per tooth, but would start at .0005. Might look at a .008 endmill to rough and if I did that I would go with .0015 per tooth with a .002 step down leaving .0002 on the floor. Then come back with the .01 to finish to depth in one pass to get a really nice finish running .0005 per tooth feedrate. Oh yeah no more than .00005 run out is what you want to hold on that as well.
