Learn Cnc Speeds & Feeds

Using a ⅛" (.125") diameter cutter instead of a ¼" (.25") cutter the required RPM for aluminum example will be:-. 500SFM X 3.82 / .125 = 15,280rpm. This would be in the range of a typical cnc router. The next issue would be the feedrate. Using an RPM of 15,280 would give a feedrate of 122 in/min.
