Recommended Speeds and Feeds for Slot Milling.
Plain Carbon Steel <500N/mm2 Carbon Steel, Alloy Steel 20HRC <800N/mm2 Alloy Steel, Tool Steel 30HRC <1000N/mm2 Alloy Steel, Tool Steel 40HRC <1300N/mm2 Aluminium & Aluminium Alloys
RPM 3900 Feed 85 mm/min RPM 3100 Feed 60 mm/min RPM 2500 Feed 40 mm/min RPM 1500 Feed 30 mm/min RPM 11200 Feed 280 mm/min

For slot milling, if depth of cut is more that 0.5D then reduce the recommended feed rate, start with 75% of the above values then increase to the above values to find the ideal parameters for your setup ideally the max run out should max <0.010mm with the maximum rigidity possible.

If the machine can't make the RPM then try the following Vf=fz*n*z (n=actual RPM of the machine)
