Down Milling. In up milling, cutter rotates against the direction of table feed. In down milling, cutter rotates along the direction of table feed. Chip load on teeth (or uncut chip thickness) increases gradually from zero at the point of engagement to maximum at the point of disengagement. Chip load on teeth (or uncut chip thickness) decreases ...

Advantages of Zero Rake Angle. It makes the tooltip stronger and makes the tool last longer than a positive rake tool. Compared to a negative rake tool, it makes cutting easier by reducing chip thickness, cutting force, cutting temperature, etc. It uses less power than a negative rake tool because it cuts down on the force needed to cut.

Climb Milling vs. Conventional Milling. There are two distinct ways to cut materials when milling: Conventional Milling (Up) and Climb Milling (Down). The difference between these two techniques is the relationship of the rotation of the cutter to the direction of feed. In Conventional Milling, the cutter rotates against the direction of the feed.

Disadvantages of climb milling. In contrast to downcut milling, in upcut milling the tool is guided against the direction of rotation. Thus, the chip thickness starts at zero and keeps increasing. Since the cutting edge has to be driven into the cut, higher temperatures and a polishing effect are created on the surface of the workpiece.
