Interesting I did not know that!

I spent a lot of time watching YouTube videos of people running aggressive production toolpaths on big CNC machines (Vertical Machining Centers mainly). After watching a bunch of those I was always pushing my milling machine and old CNC router to see what they could do. Hard to keep up with a VMC though!

Here's a fun example of what the big machines can do:




The page here recommends that tools under 1/8" be kept to 0.25x diameter max DOC when slotting. Tools 1/8" diameter and above can go to 1.5x diameter DOC when slotting. 1.5x diameter DOC is recommended for all tools when profiling (only one side of tool touching workpiece). If the machine is rigid enough then it's good to go with the maximum DOC possible as that way you're using more of the tool and tool life will go up!
