Default Router Cutting Speeds

This may sound like a dumb question, but I'm wondering about proper router cutting speeds. I'm relatively new to wood working. I know that the larger/ heavier cut the slower I should set the speed. But I come from a metal working background and you run every different kind of metal at a different speed to get the best results. Is there like a chart somewhere that lists appropriate cutting speeds for router bits depending on type of wood?

Thanks!

HI Scott, the general rule of thumb is that the larger the cutter, the slower the speed.

There are many charts out there, but they are based more on cutter size than type of wood.

I will see if I can find one.

I think not.
In my view, if in doubt of the tool rpm, start with scrap of the same material. Start at some arbitrary slow speed, say 12,000.
Rout, note the efficiency, change speed up or down accordingly.
Where efficiency = a speed where you're not forcing the tool, not burning stock, feeding at a rate that = the cut rate and doing it safely. All essentially arbitrary!

Charts, whilst reasonable starting points, are just good guesses.
An alloy in the metal shop can be counted on to be the same sample to sample, wood & wood products cannot.
Moreover, the cutter config. is always variable. There is no such thing, e.g., that says a 3/16 x 3/8 ogee at full depth in oak, should have a feed rate of x. You have to test for the best feed rate, depth of cut and RPM.
Routs.
