I usually take a couple of roughing and finishing cuts while setting up my DRO for a new job and you get a feel for this kind of thing after some time cutting a wide range of materials.
If in doubt I consult Machinery's Handbook, if you don't have a copy I recommend you shop for one on Amazon or eBay as they're a brilliant book for reference and for general leafing through and reading, you'd be surprised what you discover while reading any given copy of Machinery's Handbook, I have a copy from the 1950s and one from the late 1980s
