Conventional cut

Also called conventional milling, up milling, up cut

Feeding against the cutter's rotation, so each chip starts at zero thickness and builds to full. The tool rubs before it bites, which work-hardens the surface and dulls edges, but cutting force pushes away from the work rather than dragging it in. The safe default on any machine with backlash.

Top view of a cutter rotating clockwise and feeding left, so the flute enters at zero chip thickness and exits at full. The chip is drawn as a comma widening toward exit; a force arrow pushes the work away from the cutter.
