It doesn't expect anything, as the speeds and feeds will need to be calculated for your cut parameters and tooling.

 

As an example I use a 1/2" four flute variable helix end mill up to 1.5*Ø, 10% radial cut at 8000 RPM and 168 IPM in mild steels, and that's fairly conservative. Feedrates can go as high as 240 IPM with no ill effects, and that is a general purpose AlTiN coated end mill.

 

If you want a good calculator for HSM toolpaths I highly recommend HSMAdvisor: https://hsmadvisor.com/

 

Very satisfied customer is all, I have no relation to the company.
