Speed & feed settings vary a lot from machine to machine, a lot of it is to do with how rigid the CNC machine is. The best way to sort out speed & feed settings is to experiment yourself until you find settings that work well for you.
Manufacturers speed & feed settings tend to be for industrial machines which generally speaking are more rigid than the hobby type machines many buy so reaching these sorts of settings may well not be possible for you.
Not familiar with your particular machine but it doesn't look to be that rigid, for that reason alone I would start off with a much slower feed rate & DOC & then work up. Something else that will help with tool deflection especially with larger bits like this is to use the largest shank diameter bit you can
