Abstract

The invention discloses a machining method for a special-shaped deep groove of a titanium alloy part. The method comprises the following steps that a, a substrate, a coating and an outline structure of a numerical control cutting tool are improved according to characteristics of the to-be-machined titanium alloy part, so that the machining efficiency and the machining precision are improved; b, the machining method and a machining path for the special-shaped deep groove are improved according to a stress analysis structure and a cutting test structure that axial cutting force on the numerical control cutting tool is far greater than radial cutting force on the numerical control cutting tool in a cutting state; and c, the numerical control cutting tool is prepared, the titanium alloy part is mounted on a numerical control machine tool, a zero point is aligned, and numerical control machining is conducted to obtain the titanium alloy part provided with the special-shaped deep groove. The problems that the machining size of the precision deep groove in an inner cavity of the titanium alloy part is difficult to control, and the cutting tool is frequently broken are solved, smooth new aircraft development is guaranteed, and the development period is shortened. Part scrapping caused by an out-of-tolerance size of a groove profile is avoided, high cutting tool consumption is reduced, and the cost is lowered. New concepts for machining of the titanium alloy part are developed.

Description

technical field [0001] The invention relates to the technical field of aero-engine structure processing, in particular to a method for processing special-shaped deep grooves of titanium alloy parts. Background technique [0002] The performance requirements of the new generation of aero-engines are getting higher and higher, and the structure and shape of parts are becoming more and more complex. The processing of titanium alloy casing cavity has always been a major difficulty in scientific research and production. TC4 titanium alloy is light in material and its density is only 60% of that of ordinary steel. %, the strength exceeds many alloy steels, and parts with high unit strength and good rigidity can be produced, so a large number of aircraft engine components use titanium alloys, but their melting point is higher, 1720 degrees Celsius; it has high plasticity and is easy to process and deform , and has the characteristics of small thermal conductivity, low elastic modul...
