Thin-wall appearance part machining process

Abstract

The invention discloses a thin-wall appearance part machining process which comprises a step of roughing a mounting surface: roughly machining a raw material by adopting a disc milling cutter, roughlydigging a cavity surface of the raw material by adopting a rough milling cutter, removing residual materials at corners, and preliminarily forming a mounting surface of a workpiece; a step of performing appearance surface finish machining: conducting finish machining on a surface opposite to the mounting surface to the designated size to form an appearance surface by using the disc milling cutter, a ball cutter and a forming cutter; a step of grinding the appearance surface: grinding an appearance surface and polishing the appearance surface; a step of performing fine machining on the mounting surface: reversely clamping and fixing a semi-finished product through a suction cup clamp and repeatedly performing roughing and finish machining on the mounting surface; and a step of performing powder spraying processing: carrying out powder spraying treatment on the appearance surface. By means of the mode, an appearance part is subjected to material removing machining, finish machining is conducted after multiple times of roughing, the workpiece precision is guaranteed, the multi-curved-surface precision machining of a thin-wall part of the appearance part can be effectively conducted,meanwhile, the requirement of the appearance part for the attractive appearance can be met, and the machining precision and quality can be improved.

Description

technical field [0001] The invention relates to the technical field of appearance part processing, in particular to a thin-walled appearance part processing technology. Background technique [0002] In the field of aviation, the seat system is an appearance part, which has relatively high requirements on appearance. The treatment and manufacture of the appearance is an important key step in the workpiece processing technology. Since the final product of the seat board has a wall thickness of 2mm, it is a thin-walled part, and its curved surface shape is relatively complicated. Thin-walled parts generally refer to workpieces with a wall thickness ≤ 3mm. [0003] It is difficult to use ordinary processing methods (stamping, bending, etc.), and the processed workpieces are also easily deformed, which cannot meet the required standards at all. After all the work is done, grinding and polishing are carried out, because the workpiece is thin and deformed, and finally Will affect...

Problems solved by technology

[0003] It is difficult to use ordinary processing methods (stamping, bending, etc.), and the processed workpieces are also easily deformed, which cannot meet the required standards at all. After all the work is done, grinding and polishing are carried out, because the workpiece is thin and deformed, and finally Will affect the accuracy of the workpiece

[0004] In order not to affect the quality of the workpiece, at present, the entire solid aluminum part is processed by removing material, and the material removal rate reaches 90% or above. The existing processing technology of this material removal method has low efficiency and is also It is not easy to guarantee the quality of the seat board
