Difference Between Up Milling and Down Milling

Milling is one type of conventional machining process primarily for generating flat or stepped surfaces. In peripheral milling, cutting velocity is imparted by rotating the milling cutter about a fixed horizontal axis; whereas, the feed rate is imparted by moving the workpiece (basically worktable) against the rotating milling cutter.

Milling (machining) - Wikipedia

In peripheral milling, the cutting action occurs primarily along the circumference of the cutter, so that the cross section of the milled surface ends up receiving the shape of the cutter. In this case the blades of the cutter can be seen as scooping out material from the work piece. Peripheral milling is well suited to the cutting of deep ...

How to Explain Peripheral Milling to a Five-Year-Old ...

Peripheral milling is a machining process in which the milling cutter is placed parallel to the workpiece. In other words, the milling cutter is positioned so that the sides of the cutter grind away at the top of the workpiece. This is in stark contrast to face milling in which the very tip of the cutter presses against the workpiece.
