End milling

Depth of cut

The depth of cut of solid end mills needs to be set appropriately according to the machining method, workpiece material and cutting edge geometry.

The depth of cut is set at values found by multiplying the diameter or ball nose radius by a fixed coefficient. The image to the right shows a depth of cut standard for 2-flute, square corner, coated carbide end mill. If the workpiece materials are harder, the depth of cut should be decreased.
