Embodiment

[0020] The fixture set used for roughing, semi-finishing and finishing the first side of the part includes such as figure 1 The shown fixtures for rough machining and semi-finishing of ribbed surfaces; and figure 2 Fixtures for rough machining, semi-finishing and finishing parts without ribs shown in the edge; figure 1 and 2 It can be seen that the tooling fixture includes a support plate 1 on which a parallel iron 3 and a support 2 matching the parts are arranged. The shim 3 plays the role of auxiliary support for the part. There are four shims 3 with threaded holes in the shim 3, which are respectively located on both sides of the width direction of the part 2. They are connected by screws to fix the part 2 and the tooling to prevent the Part movement caused by collision or excessive cutting force. The tooling is simple, the manufacturing period is short, and the use is convenient.

Abstract

The invention discloses a method for machining a thin web titanium alloy edge strip, wherein the method is convenient to operate and capable of eliminating part deformations. The method for machining the thin web titanium alloy edge strip comprises the following steps in order: rough machining, semi-finish machining and finish machining; in the process of rough machining, firstly, a hard alloy end mill is adopted for rough machining of a part at a large cutting depth, a low rotating speed and a low feed speed; and secondly, a clamped indexable milling cutter is adopted as a machining cutter for equal-height cutting machining at a small cutting depth in such a manner of fast feed. The method for machining the thin web titanium alloy edge strip is capable of quickly removing black allowance and improving the machining efficiency; besides, the allowance of each portion is uniform, which is favorable for programming during semi-finish machining of the part, and further, machining cutting can be more steady.

Description

technical field [0001] The invention relates to a processing method, in particular to a processing method of a thin web titanium alloy flange. Background technique [0002] It is known that the web of the special-shaped curved surface shows a nonlinear change, and belongs to a typical large-scale thin web special-shaped part. At present, the processing steps of this kind of parts are divided into rough machining, semi-finishing machining and finishing machining. Layer cutting is used for rough machining and finishing machining, and the machining efficiency is low. Due to the large removal allowance and excessive deformation during machining, it is difficult to guarantee Web thickness dimensional accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing method for a thin-web titanium alloy flange that is easy to operate, improves the metal removal rate, and reduces the deformation of parts. [0004]...
