The Axia depth of cut is also called Stepdown and Cut depth. It is designated by ap or ADOC. The maximum possible depth depends mainly on the cutter's diameter. For large diameter cutters (Above 3/4″, 20 mm), It is up to 4D (4 times the diameter). For small diameter cutters (Below 1/8″, 3 mm) it is up to 10D.

Slotting: A 4-flute option is the best choice, as the lower flute count results in larger flute valleys and more efficient chip evacuation. Finishing: When finishing in a ferrous material, a high flute count is …

At a given surface speed, a 4 flute end mill can take 4 cuts at a given chip load (chip thickness) while a 2 flute end mill only takes half as many. So the 4 flute end mill might have 2x the Material Removal Rate. This is why we see cutters with many flutes become popular in challenging materials that only allow fairly slow surface speeds.

End mills are most popular for slot milling because they can withstand the high cutting forces. The end mills are also versatile, with a variety of materials and sizes available. The end mill designs can also be specialized to prevent chatter challenges, thus ensuring a high quality finish. But there are other slot milling techniques.

Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations.

Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. The teeth are angled in two directions …

A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing them to provide fast cuts, smooth finishes, and long tool life.

One is cut with an end mill, and terminates with a 90 degree wall at the inner end. The other style is cut with a keyway cutter, which is essentially a small circular saw the width of the keyway, and leaves a dished inner end. The end mill style would seem to leave a stress concentration point at the 90 degree termination. The dished style is ...

Keep a low cut width (or cut depth if you're talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 2-3x chip load will be right for the finish pass.

The idea, is to rough out a pocket, profile, or 3D surface by plunging either a twist drill, an end mill, or a special-purpose tool straight down into the material.

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.

It is a machining procedure that uses a spinning tool with many cutting edges. A slot milling operation's main determinants are the workpiece's material properties and the necessary dimensions of the slot (width, depth, and undercut).. The proper selection of tools, feed rate, speed, and cooling fluids can all have a significant impact on …

When one end wears out, switch to the opposite end for two times the life of a standard carbide end mill. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Use them to round sharp corners on the edge of your workpiece.

For milling brass, the best tools are high-speed steel (HSS) cutters specifically designed for cutting metals.
