I use a Quickcircuit at work, and I've never had any luck running
stub endmills any smaller than 8 mils into 1oz board, no matter what
the feed rate. I usually try to route my boards to accomodate a
12 mil or larger bits, only running the 8 mil for those sections that
absolutely need it like fine pitch part pads. The 12 mil bit I run
at 3 inches per minute, and the 8 mil at 1 inch per minute. Perhaps
someone else has tips on the science of how to properly feed these
small end mills but this is what I've learned empirically.
