In the process of CNC turning and milling titanium alloy, the matters that should be paid attention to are:
(1) Due to the small modulus of elasticity of titanium alloy, the clamping deformation and force deformation of the workpiece during machining are large, which will reduce the processing accuracy of the workpiece; The clamping force should not be too large when the workpiece is installed, and auxiliary support can be added when necessary.

The drilling is semi-closed CNC cutting. The cutting temperature is very high in the process of drilling titanium alloy, the rebound after drilling is large, the drill chips are long and thin, easy to stick and not easy to discharge. Drilling of titanium often causes the bit to be bitten, twisted, وما إلى ذلك وهلم جرا. لذلك, the drill bit is required to have high strength and good rigidity, and the chemical affinity between the drill bit and the titanium alloy is small. It is best to use cemented carbide drills, but the most commonly used at present is still twist drills, after taking some measures to improve, better results can also be achieved.

When high-speed milling of TC4, Gc.2, and pure titanium integral structures, down-milling is generally used. The tool slowly cuts into the titanium workpiece to reduce the heat generated and reduce the radial force.
When milling titanium alloy TC4 (تي-6Al-4V), asymmetric down milling is often used, so that the front tip of the cutter tooth first contacts the workpiece.
