These calculations are starting points and may need adjustment based on machine rigidity, tool condition, and workpiece fixturing.
For harder materials, consider reducing speeds by 10-20% for longer tool life.
Increase coolant flow for higher speeds and feeds.
For climb milling, ensure your machine has minimal backlash.
Peck drilling recommended for holes deeper than 3× diameter.
Use the largest nose radius possible for the specified surface finish.
