What Are the Cutting Characteristics of Titanium Alloy?
Titanium alloy refers to various alloy metals made by combining titanium with other metals. Titanium is an important structural metal developed in the 1950s, known for its high strength, excellent corrosion resistance, and high heat resistance. During the 1950s to 1960s, the focus was primarily on developing high-temperature titanium alloys for aircraft engines and structural titanium alloys for airframes.
Titanium alloys are mainly used to manufacture compressor components for aircraft engines, followed by structural parts for rockets, missiles, and high-speed aircraft.
When the hardness of titanium alloy exceeds HB350, cutting becomes particularly difficult, while below HB300, it tends to cause chip adhesion, making it equally challenging to machine. However, hardness is only one aspect of the difficulty in machining titanium alloys; the key lies in the combined influence of their chemical, physical, and mechanical properties on machinability. Titanium alloys exhibit the following cutting characteristics:
(1) Small Deformation Coefficient: This is a significant feature of titanium alloy machining, with a deformation coefficient less than or close to 1. The sliding friction path of the chip on the rake face increases significantly, accelerating tool wear.
(2) High Cutting Temperature: Due to the low thermal conductivity of titanium alloys (only 1/5 to 1/7 of that of 45# steel), the contact length between the chip and the rake face is extremely short. Heat generated during cutting is not easily dissipated, concentrating in a small area near the cutting zone and the cutting edge, resulting in very high cutting temperatures. Under the same cutting conditions, the cutting temperature can be more than twice as high as when cutting 45# steel.
(3) High Cutting Force per Unit Area: The main cutting force is about 20% smaller than when cutting steel. However, due to the extremely short contact length between the chip and the rake face, the cutting force per unit contact area increases significantly, making the tool prone to chipping. Additionally, due to the low elastic modulus of titanium alloys, radial forces during machining can easily cause bending deformation, leading to vibrations, increased tool wear, and reduced part accuracy. Therefore, the process system must possess sufficient rigidity.
(4) Severe Work Hardening: Owing to titanium's high chemical reactivity, at elevated cutting temperatures, it easily absorbs oxygen and nitrogen from the air, forming a hard and brittle surface layer. Simultaneously, plastic deformation during cutting also causes surface hardening. Work hardening not only reduces the fatigue strength of parts but also exacerbates tool wear, making it a critical characteristic when machining titanium alloys.
(5) Pronounced Tool Wear: After processes such as stamping, forging, and hot rolling, the blank forms a hard and brittle uneven surface layer, which is extremely prone to causing chipping, making the removal of this hardened layer one of the most challenging steps in titanium alloy machining. Furthermore, due to titanium alloy's strong chemical affinity with tool materials, under conditions of high cutting temperature and high cutting force per unit area, tools are highly susceptible to adhesive wear. When turning titanium alloys, wear on the rake face can sometimes be more severe than on the flank face. At feed rates f < 0.1 mm/r, wear primarily occurs on the flank face; when f > 0.2 mm/r, wear appears on the rake face. For finish and semi-finish turning with carbide tools, flank wear VBmax less than 0.4 mm is considered appropriate.
In milling operations, due to the low thermal conductivity of titanium alloy materials and the extremely short contact length between the chip and the rake face, heat generated during cutting is not easily dissipated and concentrates in a small area near the cutting deformation zone and the cutting edge. During machining, the cutting edge experiences extremely high temperatures, significantly reducing tool life. For titanium alloy Ti6Al4V, provided that tool strength and machine power allow, the cutting temperature is the key factor affecting tool life, rather than the magnitude of the cutting force.
