Processing of titanium and alloys
Processing Challenges
Many titanium parts have complex shapes with shallow, narrow or large and deep pockets, thin walls and chamfers. Successful machining of these shapes inevitably requires longer tools, which can lead to tool deformation. In addition, titanium alloys have:.
- high strength-to-weight ratio;
- Lower modulus of elasticity compared to steel;,
- higher corrosion resistance than steel,
- low thermal conductivity.
These properties cause vibration during cutting, which leads to rapid wear of the cutting edge. Titanium does not conduct heat well. Therefore, machining it requires tools of high red resistance.
Optimisation of machining
Since titanium retains its hardness at high temperatures, the cutting edge is subjected to extreme loads and considerable heat is generated in the cutting zone. Therefore, selecting the right cutter grade and geometry is key to successful machining. Uncoated carbide grades and PVD coated inserts have proven excellent for cutting titanium,
Cutting Modes
While positive rake angle geometries are generally preferred, tools with slightly more negative rake angles are capable of machining at significantly higher feeds, which can be as much as 0.5 mm per tooth. The minimum feed rate when milling titanium is usually 0.1 mm per tooth. The spindle speed can be reduced in order to obtain the original feed rate. Incorrect spindle speeds can reduce tool life by as much as 95% at the minimum feed rate.
