Cutting Speeds
950. 760. 640. Speeds in Surface Feet per Minute are specified for High-Speed Steel drill bits, and are approximate for normal drilling operations. Speeds should be halved when using Carbon Steel bits and can be doubled for Carbide bits. Use coolant judiciously. For Milling operations speeds may be increased by 50%.

milling AR 400 need some advice please
Also need to machine to OD to a specified size and then mill a step in it to a smaller Dia.. My question is what starting feeds and speeds would you recommend? I have carbide mills and the machine is a 7HP maintained Fryer toolroom mill. I was thinking of starting at about 1200 RPM and .005 IPT. 4 flute mill. Do I need slower speed? Bigger cut?
A Machinist's Guide to Trochoidal and Peel Milling
To convert that to cubic inches per minute, we'll multiply that by our feedrate. 0.1875 square inches x 38.4 inches per minute = 3.36 cubic inches per minute. Now let's compare that to peel milling. To maintain the same 0.003″ chip thickness at 0.050″ stepover, the feed can be increased to 0.0051″ per tooth.
