First, titanium alloys have low thermal conductivity, which is only 1/4 of steel, 1/13 of aluminum, and 1/25 of copper. Due to slow heat dissipation in the cutting zone, it is not conducive to heat balance. During the cutting process, the heat dissipation and cooling effects are very poor. It is easy to form high temperatures in the cutting zone. The deformation of the parts after machining is large, and the cutting tool torque increases and the cutting edge wears fast. Reduced durability. Secondly, the low thermal conductivity of the titanium alloy makes it difficult for the heat of cutting to dissipate in the small area around the cutting blade. The rake face has increased friction, it is not easy to remove chips, cutting heat is not easily dissipated, and tool wear is accelerated. Finally, titanium alloys have high chemical activity and can easily react with tool materials at high temperatures to form solubilising and diffusion, resulting in sticking, burning, and cutting. Tool material selection should meet the following requirements: 1) Adequate hardness. The hardness of the tool must be much larger than that of aluminum-titanium alloy. 2) Adequate strength and toughness. Because the cutters take great torque and cutting forces when cutting aluminum-titanium alloys, they must have sufficient strength and toughness. 3) Sufficient wear resistance. Due to the toughness of the titanium alloy, the cutting edge must be sharp during machining, so the tool material must have sufficient wear resistance so as to reduce the work hardening. This is an important parameter for selecting a titanium alloy tool. 4) The affinity of tool material and titanium alloy is poor. Due to the high chemical activity of aluminum-titanium alloys, it is necessary to prevent the tool materials and aluminum-titanium alloys from forming a solution or diffusion alloy, resulting in sticking and burning.
