The maximum possible ap is related to the tool’s diameter and is sometimes measured in diameter multiples. For example, a 3D 1/2″ endmill can cut at a depth of cut of up to 1.5″.
( The Axial Depth of Cut is closely related to the radial depth of cut. In most cases, you need to consider both when making decisions. Learn More in our In-Depth Depth of Cut guide.
