First off, this is my nemesis, finishing tall profiles in one pass with no chatter. I can never seem to find the magic recipe.
Material = 6061. Profile is 1.112" x .312" x 1.410" tall. Two of the outside corners have a .120" rad. The other two a .010" rad.
Can't finish with Z steps. Has to be one pass. I am using a dead-sharp 1/2" M.A.Ford X-AL 3fl in a Schunk hydro.
I have been all over the map with all parameters. I've tried leaving anywhere from .050" to .010" for finish.
SFM everywhere from about 300 up to about 1800. Chip load from .0015" up to .006". I can't find the sweet spot.
Also increasing the feed around outside corners anywhere from 110% to 175%.
So far the best I can do is .015" leave, 524sfm, .002"ipt, and 120% feed around corners.
But the finish still isn't great. And its still chattering, especially around the outside corners. Even with a brand new tool.
I am sure it is the super narrow width of the material. But, can't figure out how to overcome it.
I'm giving up for tonight. Tomorrow I'm going to try like ZERO RPM (not really zero, but super slow). I don't know what else to do.
Also, I'm kind of stuck with this tool. I'm limited to what I have on hand with a 1.5" flute and square corner.
I'm real close to running out of extra stock. And, I have to be running tomorrow. I'm stumped. Where would you go from here?
