This page will cover some baseline speeds and feeds for common materials we use. However, we first need to cover machining material categories.how to determine amount and speed at which material is cut off of the stock.

ISO Material Groups
When determining feeds and speeds for a given manufacturer’s tool, you need to know what material it is being used for. This is where ISO standards come into play. Typically we work in P (Steel) and N (Non-Ferrous, Aluminum). You will then select your material number based on the alloy you are using and its material properties.

Machine Considerations
For our machining, we will largely be machine limited on speeds and feeds.
Key limitations:
Power and Torque

a given cut. I typically stick to under half of the machine limit at most.
...
Speed:
In X and Y, the machine is limited to 300 inches per minute (IPM)
In Z the machine feed limit is 230 IPM
