Abstract

The invention discloses a machining method of a frame part, which comprises the following steps of: roughly turning an outer circle and an inner hole of the part, and reserving machining allowance; threading holes are formed in the circumferential surface of the part; the outer circle and the inner hole of the part are subjected to finish turning, stress deformation generated during threading hole manufacturing is repaired while burrs are removed, it is guaranteed that the part meets the requirements for design size precision and form and location tolerance, and cutting is conducted after a clamping part is reserved; after the clamping part is clamped, the part is aligned, the circumferential net structure of the part is linearly cut, and a workpiece is formed; and the workpiece and the clamping part are cut off to ensure that the length size of the workpiece meets requirements. According to the machining method, the problem of machining deformation of the frame parts is solved, the product quality is stable, the requirements of design drawings are met, and the product percent of pass and the machining efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a machining method for frame parts. Background technique [0002] Frame parts are common types in machining. In recent years, with the development of my country's aerospace industry, the application proportion of such parts has increased year by year. In order to reduce the weight of parts in aerospace applications, and because the material is mostly the national military standard stainless steel 1Cr18Ni9Ti, the parts have the characteristics of small size, thin wall, difficult processing, and high precision of matching dimensions. Since the circumferential network structure is easily deformed during the milling process, it is difficult to guarantee the dimensional tolerance and shape tolerance accuracy of the product, and cannot meet the design requirements. The main difficulties in processing this part are: more allowances for removing the circumferential network structure,...
