The trick is to not get it hot enough to melt I guess. Watched a video the

to better see what it was cutting and had an instant clog up of the mill.
Yes, absolutely! The softer the alloy, the less heat it
takes to get it to the "gummy" state.
Coolant works wonders, the whole trick is to make sure the
workpiece is stiff enough for the cutting edge to CUT,
rather than MASH, through the material. Heating some grades
of aluminum just to about body temperature (100F - 37 C)
will get it into that range when the cutter hits it.
