According to the Atlas MOLO, the optimum surface speed for milling is about 2/3 that of the optimum speed for turning.. This is probably for HSS cutters. Once the recommended SFM is known, the MOLO has a table that gives the RPM required with various size and type milling cutters to get a given surface speed. There are copies of a couple MOLO's in Downloads. The speed tables themselves are also there by themselves.
