I am going to mill about 100 notches into brass. 1/4" end mill. 3/8" full depth (cannot step down bit by bit to the 3/8"). Have to go through a 3/8" piece. (Will be notching out a 3/8 by 3/8 square by 1/4 wide). What end mill would be best? I am guessing a two-flute, like for aluminum but is there something better?
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.

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 ...
It is a machining procedure that uses a spinning tool with many cutting edges.

Re: Tips on milling brass. by knudsen » Wed Apr 14, 2010 6:34 pm. No cutting fluid, coolant or oil, go dry. It does tend to grab cutters, which means you want the piece secured very well and no excessive slop in any axis of the mill. I have little milling experience on brass, but considerable turning experience.
I was wondering what the best machine and setup would be to cut a thin slot, .020", about 1/4" to 3/8" deep, into brass bar, maybe 10"-14" in length. I was thinking a slot saw blade or a micro drill bit. Would a horizontal mill or vertical mill be better? From what I have gathered it seems like a vertical mill is more versatile.
Alternatively this might work if you have a rotary table, pilot to depth say a 3/4" hole, change for a 3/4" endmill, offset the table 1/8" on one axis, plunge to depth and rotate the table 360 deg which should give you a 1" flat bottom hole with square corners. Others may know better. oldtiffie. Member.

The 2 and 3 flute end mills have more back clearance behind the cutting edge for cutting soft materials. This includes aluminum, wood, plastic, etc. The 4 and more flute ones have less back clearance for a stronger cutting edge for cutting steel and the harder materials. You can make a 4 flute act like a 2 flute in a slot by milling out the ...

Other than the tendency to run hotter due to surface speed issues, the material doesn't know the difference between being cut twice a revolution by a two flute end mill at 6000 rpm or 4 times by a four flute end mill at 3000 rpm. Hence, switching from a two flute to a four flute is like doubling your spindle speed.
Depends how wide the slot is. It is fastest to punch though and "chain drill" with the end mill every 1/2 diameter of the mill, then keep the mill down and transverse the slot again to clean it up. This is how I was taught by an old shop guy. This way works for me. We call this Chop Milling.

Trying to gouge out a max performance cut is very likely to snap off that 2 flute endmill, while the 4 flute may hold up better. Key slotting with a 2 flute endmill, especially if you try to cut in both directions, will almost certainly result in an oversized slot due to flex. Horizontal mill is THE way to slot accurately.
