SS 316 feeds and speed

[angelalayon1]

Hello,

I have been running a Tormach PCNC 1100 for about 7 month. Most of the time I cut plastics, Aluminum, Delrin, etc. But they need to rough some part out of SS316. There are a lot of ideas about feeds and speed for that kind of material. I got some 1/4 endmill 4 flutes special for that material, and the feeds and speeds that they recommend me are:

IPT = 0.0015
SFM = 265

In my opinion that looks a little fast but I do not know what you guys recommend me

I am not a native english speaker so sorry for my gramatical mistakes

That seems about correct with flood coolant.

thank you men.

Do you have any extra advice for depth of cut.

It depends on the cutting strategy. Normally I try to go full depth, with maybe 0.035 inch (1mm) step over.
