An end mill, for instance, will need to be properly perpendicular to the work surface. Otherwise, the work may not turn out accurately, and the machine may get damaged. Leveling is crucial to manufacturing high-quality machine parts. It is used on automation systems and additive manufacturing facilities.

Typically, the process of cutting with an end mill utilizes both the end of the cutter, as well as the sides, which allows for pocketing and ramped cutting procedures. Face milling, in general, is defined as the process of cutting surfaces that are perpendicular to the cutter axis, or the faces of a part.

Groove or slot milling. Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or non-straight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.

Depths of cut. Depths of cut when end milling include the axial depth of cut (ap) and the width of cut (ae).Examples of ap and ae when shoulder milling with a square end mill are as shown in the image below, while for slotting, ae is equivalent to the diameter D 1. When shoulder milling with a ball nose end mill, the pick feed, (pf) is often used instead of ae.

An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. While a drill bit can only cut in the axial direction, most milling bits can cut in the radial direction. Not all mills can cut axially; those designed to cut axially are known as end mills.

With CNC milling, the radius of your end mill is the radius of any internal corner, so you will almost never have a perfectly square corner on the inside of a milled object. Smaller and smaller end mills can be used for each pass to clean up an edge and get the part to the final dimension and shape.
