I'm still experimenting and getting used to my Mini Mill and learning how to set-up jobs going from Fusion 360 to actually machining pieces in aluminum. I've been noticing when cutting the outside shape of a plate that I don't get consistent finishes on all sides. If cutting the perimeter of a square plate, I get better surface finishes along the y axis than I do along the x axis. Along the x axis, I get better surface finishes in the back than in the front of a work piece. The front surface of the work piece tends to get gouges. Rather than here a consistent cutting sound from the bit, I here it bite into the material every so often. I thought it was chatter, but it is very inconsistent. Any ideas?
