End Mill Slotting Aluminum Sheet

Corner chamfer and corner radius end mills make a flat bottomed.

Rounded edge square end mills often used for slotting and pocketing cuts in mold and die making these end mills have a 90 profile with rounded corners which reduce flute breakage and chipping. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Machining a groove or slot often called full slotting involves three machined faces. Dovetail end mills create dovetail slots for joining components holding work or housing an o ring or other seal.

Ball end mills create a round bottomed groove in a workpiece. Square end mills cut a flat bottomed groove with 90 inside corners. Ball end mills also known as ball nose end mills are used for milling contoured surfaces slotting and pocketing. Rounded edge square end mills often used for slotting and pocketing cuts in mold and die making these end mills have a 90 profile with rounded corners which reduce flute breakage and chipping.

The axial cutting depth should be generally reduced to around 70 of the edge length. Each end mill has flutes on its cutting head that carry the removed material away from the workpiece to prevent damage to the end mill or workpiece. Slots closed at both ends are pockets requiring end mills that can work in the axial direction full slotting with an end mill is a demanding operation.
