For example, if I use a 1/2" 4 flute square end mill, is 0.200" DOC too small or too large of a cut?
Any help or pointers towards help would be appreciated.

Indie,
What you are asking about is "feeds and speeds". You can do a deep cut if the material is fed at a slow speed or if the material is soft. Specially designed tools also have recommended speeds and feeds that need to be used to use the tool at it's most efficient or what to avoid that might damage the tool. It is an art for machinists to know how to determine all of the setable parameters on the machine. Check here...

Here is one for drilling,

This is a representative chart that might be a good reference. Rememer that coolant also will play a role in machining speeds and feeds. 0.200" DOC does seem a bit deep off the top of my head, though.

Hope this helps,
