While CNC machining titanium offers numerous advantages, it also presents certain challenges during CNC machining:

· Hardness: Titanium is a relatively hard material, which can lead to increased tool wear and reduced machining efficiency.

· Work hardening: Titanium tends to work harden as it is machined, which can make it even harder and more difficult to cut. This can further exacerbate tool wear and reduce machining efficiency.

· Tendency to gall: Titanium can gall, which occurs when the workpiece material adheres to the cutting tool, causing damage to both. This can result in poor surface finishes and reduced tool life.

· High cutting temperatures: Machining titanium generates high cutting temperatures, which can contribute to tool wear and workpiece distortion.
