Any Online Sources For Speed & Feed Calculations?

I'm working with a Haas SL 20 and I'm trying to optimize cycle times, anything would be a help as I'm just guessing right now. Thanks.

What are you trying to cut?? 2D, 3D,..... That link is nice but it's not even close to what you would need to do the job right.

Try this link and follow the leads to myTECshop. There you will find an online calculator that works pretty well.

so as a rule of thumb. and anyone offering better please do

carbide insert (sfm) milling

4140-500 ....-P hardened 400
A-2 -600
a-2 annealed 400-500
crs case hard 400
hard mill (A2)-400-450
crs-1000
6160-1300
nylon-balls out rpm -.016 per tooth-.020
phenolic- glad i dont deal with this anymore- like a2, run wet, carb EM only
g4 - run wet, hold genitials for extra safety, carbide EM only

slow speeds and feeds down 30% when pretty secretary walks by
