Whether or not there's chatter depends on the changing chip thickness. We see that whether it's conventional milling or climb milling and the chatter is still there. There is some conventional wisdom that says that the climb milling pushes the workpiece into the fixture and so that can make it a little stiffer. That's more comment about the fixturing than it is about whether or not you're using the machine correctly. We really don't see a big difference in the in the cutting performance. The locations of the stable zones are the same. The depth of cut that you can achieve is the same. The mechanism that causes the vibration is the same and so from that point of view not much of a difference.
