1. Use a blade with a positive angle geometry to reduce cutting force, cutting heat and deformation of the titanium rod.
2. Maintain a constant feed to avoid hardening of the workpiece. The tool should always be in the feed state during the cutting process. The radial tool engagement during milling should be 30% of the radius.
3. Use high-pressure and high-flow cutting fluid to ensure the thermal stability of the titanium rod processing process and avoid workpiece surface degeneration and tool damage caused by excessive temperature.

4. Keep the blade edge sharp. Blunt tools are the cause of heat accumulation and wear, which can easily lead to tool failure.
5. Process the titanium alloy in a softer state as much as possible, because the material becomes difficult to process after quenching, and heat treatment increases the strength of the material and increases the wear of the blade.
6. Use a large tool tip arc radius or chamfer to insert as much of the cutting edge as possible into the cutting. This reduces cutting force and heat at each point and avoids local breakage. When milling titanium alloy, among the cutting parameters, cutting speed has a great influence on tool life, followed by radial tool engagement (milling depth).
