Hello, I am going to be machining some 4130 here soon. I have mostly done aluminum. My question is, how do I calculate the speeds and feeds for steel. I have a calculator on my phone, but it doesnt go off material just tool size. I normally ran the machine at 1500 to 2k for aluminum, but with steel, think this may cause problems. I am using master cam, so it gives me some basic numbers, but I know I can usually bump em up. Im just wondering how high I can bump em. I will be running the part on a HAAS TM1. Thank you.

Ok, found a website and it calculated to about 1200 RPM for a 1/8 endmill and 800 for a 1/2 endmill.
Those are pretty good starting numbers.

Does anyone know of an app for the Iphone, that would list the cs for materials? I dont want to have to keep pulling up the internet to check for different materials. Thank you.
Maybe save the relevant tables as documents?

What kind of tools are you using. Hss, carbide? Coated or uncoated? That makes a big difference. Your numbers seem low for carbide but are not far off for hss.

It all depends what you are doing and with what tools, Running carbide 110m/min 0.05 a tooth will cut most steels but you can go alot faster than that. Speak to whoever you buy tooling from tell them what tools your using, depth/width of cut and they will give you the proper speeds and feeds.
If your local rep is useless google whoever makes you tooling they normally publish spped and feed data online.
Im going to run hss, then thinkin of moving to carbide if the first few parts come out right. Also, this question may be opening a can of worms, but who makes good tooling that is made in American. Thank you.
All of the major tool vendors supply made in USA tooling. Just check their catalog listings.
