【Abstract】 Aiming at the increasing demand for high manufacturing performance of complex deep hole structure parts in high-end equipment fields such as energy, power, national defense, vehicle and aerospace, this paper studies the machining of titanium alloy complex deep-hole structural parts, which is the titanium alloy bottle boring deep-hole. A deep hole diameter changing tool and tool driving system was developed, and the realization of the structure of the deep hole diameter changing tool, the reasonable matching of geometric parameters and cutting parameters, and the titanium alloy diameter changing process was carried out. The machining process was stable and the machining effect was good. It provides basic theory and key technical support for deep hole contour machining of titanium alloy, and solves the key technical problems that need to be solved in the manufacture of titanium alloy taper deep hole parts in production.更多还原
