Milling Titanium Parts

When milling titanium, the tool is required to work with at least a minimum feed – typically 0.1mm per tooth. If there is still a tendency to vibrate, then the problem of broken inserts or shortened tool life will be inevitable. Possible solutions include accurately calculating the feed per tooth and making sure it is at least 0.1mm.

Alternatively, the spindle speed can be reduced to achieve the original feed rate. If the minimum feed per tooth is used and the spindle speed is not correct, the impact on tool life can be as high as 95%. Lowering the spindle speed usually improves tool life.

Once stable conditions are established, the spindle speed and feed can be increased accordingly for optimum performance. Another option is to take some inserts out of the cutter or choose a cutter with fewer inserts.
