The default values are just placeholders, especially in V-Carve Desktop. The folks at Vectric don’t know which CNC machine you have (hobby, industrial, etc.), so you should always check if the settings are accurate for your particular machine and the material you are cutting. I believe, in V-Carve, that once you change the values, they become the default for the next time you use the software.
I am not sure if the default values in Carbide Create match the Feeds and Speeds chart or not, but I know that the values in the Feeds and Speeds chart are different based upon tool selected, the material you are cutting, and the machine you are using (Nomad vs. SO3).
So, you are reading things correctly, but you are reading too much into it Figure out what works best for you for your machine, your bit, and the material you are cutting, and write it down in a log book. Then, when you are ready to cut something, you can set the numbers appropriately.
