So I am playing with aluminum and doing very small details. I lowered all the settings that CC suggested by quite a bit (feeds, depth…) and it still sounds really bad and snapped a bit 3 seconds in. I finally manually set it to 20% feed in Carbide Motion and it seems to be OK. But curious what is the right way to set this and I will admit I only understand a few of these settings.
#112 - 0.063 end
Stepover 0.028 <-- Did not change
Spindle 9000 <–Did not change
And I set the center just a hair above the work so the first pass would not be too harsh (like a business card thickness instead of paper).
These are small 1.5" discs and just trying a simple gear design as a pocket.
