Subject: Magnesium Machining
|
Can someone help me giving me cutting speed and different parameters in order to machining magnesium in safe conditions.
Thanks.
Xav.

we cut a mg rod with 3 centimiter diameter, using a new sharp alloy knife, in low speed mode(i dont know the exact value, i am not the machiner). the tempareture growth is not noticable. It is the little scraps cutting from the rod that is dangerous. Be careful to deal with them.

What type of machines are being used and what machining is being done. shapers, planers, mills, saws, drills, reamers, tapping, turning, threading, grinding ?? Magnesium is the most easily machinable of all metals. Speeds up to 5000 SFM have been used at feeds of 0.030" per revolution. The speed and feed naturally vary depending on the surface finish desired. The cutting tools used on magnesium should have relief and clearance angles that are sufficiently large to eliminate contact and rubbing of the tool beyond the cutting edge. Magnesium can be machined dry or with a coolant. Dry machining is usually cleaner and more profitable. Safe and efficient chip removal is important when dry machining. There are not usually problems with thermal expansion, however, high machining speeds and feeds with a large amount of metal removal can cause considerable heating.

I've seen it milled with a 3/4" rougher taking .150 at a whack - going 40 inches/minute and spinning at 1000 RPM...
The material is very soft and machinable. Depending on what you're trying to do, a cutting speed of 900-1000SPM (just a shade faster than aluminum) will suffice. Rarely are any cuts made deeper than .125 at a pass..
As far as tools go, we'll ONLY machine it dry and ONLY use HSS or HSS w/ TIcN coated endmills. Roughers to take the first passes and the FOUR-fluted mills for the finish. As far as safe conditions go, as long as it is machined dry in an area with no chgances of sparks or fire, it shouldn't be a problem.
