Titanium offers an outstanding strength-to-weight ratio and corrosion resistance, which is why it appears in aerospace and medical parts. It is also one of the more demanding materials to machine.
Why titanium is tricky
- Low thermal conductivity: heat stays at the cutting edge instead of flowing into the chip, so tools overheat.
- Work hardening: rubbing instead of cutting hardens the surface and dulls tools fast.
- Galling: the material can weld to the tool at the flank.
Best practices
- Sharp, positive-rake tools in carbide or coated grades (AlTiN).
- Moderate speeds, high feed per tooth—keep the tool cutting, not rubbing.
- Flood or high-pressure coolant to pull heat out of the zone.
- Rigid setups to avoid chatter and work hardening.
- Climb milling to reduce rubbing on entry.
Design implications
Avoid thin features that deflect under cutting force, and keep wall thickness modest. Titanium is expensive, so design for manufacturability matters even more—minimize material removal where you can.
