A processing method of titanium alloy thin-walled double-lug parts

Abstract

The invention provides a machining method for a titanium alloy thin wall double-tab part. The part contains parallel double tabs and a web arranged at the base parts of the tabs, wherein the tabs and the web are in a non-right-angle relation; a combined milling cutter is arranged and is formed by connecting three disc milling cutters and gaskets among the milling cutters in series by a central shaft; a part is clamped on a horizontal milling machine through a splicing milling tool so that the machining of tab groove cavities and the outer sides of the tabs is finished; and one angle opening milling cutter and one angle closing milling cutter are used for machining residues of opened angles and closed angles of the outer sides of the tabs of the part.

Description

technical field [0001] The application relates to the manufacture of aircraft parts, in particular to a processing method for titanium alloy thin-walled double-lug parts. Background technique [0002] In the field of mechanical processing, titanium alloy materials have characteristics that other metal materials cannot possess: high specific strength, high thermal strength, and good corrosion resistance. In particular, the biggest bottleneck in the processing of titanium alloy thin-walled double-lug parts is the difficult processing of materials, high requirements on dimensional accuracy and shape and position tolerances. Generally, rod milling cutters are used for processing on ordinary milling machines or CNC machining centers. In the actual production process, for special double-lug structures, especially when there is a dihedral angle, the lug spacing and lug flatness And when the wall thickness requirements are strict, conventional machining methods and tools cannot gua...

Problems solved by technology

In particular, the biggest bottleneck in the processing of titanium alloy thin-walled double-lug parts is the difficult processing of materials, high dimensional accuracy and high tolerance of shape and position.

Generally, rod milling cutters are used for processing on ordinary milling machines or CNC machining centers, but in the actual production process, for special double-lug structures, especially when there is a dihedral angle, at the same time, the distance between the lugs and the flatness of the lugs And when the wall thickness requirements are strict, conventional machining methods and tools cannot guarantee
