Depth of Cut AP

If the depth of cut is shallow, the revolution and feed rate can be increased.
When Slotting with end mills with 3 or larger, reduce the revolution to 50~70% and the feed rate to 40~60%.
When drilling, please set the feed rate at 1/3 or below the values above.
If the rigidity of the machine or the work materials installation is very low, or chattering and noise are generated, reduce the revolution and feed rate
proportionately.
