Face Milling vs Peripheral Milling: What's the Difference ...

The milling cutting is essentially positioned "face down" towards the top of the workpiece. When engaged, the top of the milling cutting grinds away at the top of the workpiece to remove some of its material. What Is Peripheral Milling? Peripheral milling is a machining process in which the milling cutter is placed parallel to the workpiece.

What is the difference between up milling and down milling? In up milling, cutter rotates against the direction of table feed. In down milling, cutter rotates along the direction of table feed. In down milling mode, the cutting force is directed downward, and thus it tends to press the workpiece rather than lift off.

Climb Milling vs. Conventional Milling - In The Loupe

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.

The relative motion of the tool or cutter with respect to the workpiece is the major difference between a drill press and a milling machine. A drill press is limited to only up and down motion (Z-Axis). It can cut holes into the workpiece but it is unable to cut the faces of a workpiece. So work output is limited.
