Is there any chart showing recommended surface feet per minute for various woods ?
In machining the formula is Surface Footage X 3.82 divided by the diameter of the bit.
Feed rate in inches per minute is = Chip Load ( how much each tooth of the cutter is cutting per pass) X RPM X number of teeth of the cutter.
An example in steel .
With a recommended 250 sfpm to machine tool steel ., I would run a carbide end mill at 3820rpm(250x3.82= 3820)
Charts would tell me recommended chip load so that I could calculate feed rate.
Feed rate would not be so useful as many things are hand fed by feel( in woodworking) , but I would think surface footage could come in handy.
