Currently, Process parameters mainly affect chip deformation and chip breakage.
At the same time, the merits of the process parameters are mainly evaluated by the chip morphologies, tool wear, hole-axis deflection, and hole surface roughness. The selection of reasonable tool geometry and process parameters can make the chip morphologies, tool wear, hole-axis deflection, and hole surface roughness meet the machining requirements, thus improving the machining stability, machining quality, and tool life. Among them, tool geometry parameters include rake angle, relief angle, tool approach angle, drill tip eccentricity and chip breaker size, etc., while process parameters mainly include spindle speed and feed. To obtain a good quality hole surface and high machining efficiency, machining conditions such as tool geometry parameters, process parameters, and workpiece material properties need to be fully considered. When processing TA10 workpieces, the cutting force is not large, but the contact area between the tool and the chip is small and the stress is greater, making the processing tool extremely easy to wear further, the workpiece is very easy to rebound deformation, seriously affecting the processing surface quality and causing unnecessary economic losses. Therefore, BTA deep-hole drilling is widely used.
At the same time, the BTA system has a relatively simple structure, easy operation, and higher system rigidity compared with the gun drilling system it also has better chip removal and cooling lubrication, which is convenient for observing the tool wear condition. Among them, the BTA system is widely used due to its advantages of high machining quality, wide machining range, and stable performance. The deep-hole drilling system for machining TA10 alloy can be divided into gun drilling system, BTA system, jet suction drilling system, and DF system according to its chip removal method and cooling method.
Although TA10 alloy has excellent mechanical properties, it is a typically difficult-to-machine material its high strength and high hardness lead to high requirements for deep hole drilling and it poses a challenge due to the closed environment, the difficulty of observation, and the difficulty of chip removal. TA10 pipes have good corrosion resistance, cold forming properties, and weldability and are widely used in pipeline environments with complex service environments. TA10 alloy is a near-alpha-phase titanium alloy developed to improve the crevice corrosion performance of pure titanium and is often used in many fields such as chemical, metallurgical, and petroleum.
