Sandvik Coromant – How to reduce vibration in metal cutting 30
Cutting Data
1. If possible try to decrease (or in some cases increase) the cutting speed to
move away from the vibration frequency range.
2. Normally increase the feed/tooth. In some cases with unstable condi-
tions it can be better to decrease the feed/tooth.
Down Milling / Up Milling
Generally Down Milling is recommended in almost every milling opera-
tion wherever the machine, fixturing and workpiece allows it. But in some
cases it can be favourable to use Up Milling to reduce vibration tendencies.
Especially when fixturing and/or workpiece is weak in a specific direction.
