Embodiment Construction

[0029] The embodiment of the present invention provides a processing method for plate structural parts, including: processing process design, processing allowance distribution, numerical control milling and micro-boring cutting;

[0030] The process flow design includes:

[0031] The inner shape is processed by CNC milling, leaving a margin of 2mm;

[0032] Eliminate stress during processing by artificial aging;

[0033] 0.15mm ~ 0.2mm boring amount is reserved from the inner shape to the size installation surface by CNC milling;

[0034] Fine boring datum surface and mounting surface to ensure various shape and position tolerances;

[0035] Manual grinding assists fine boring, removes local high points of datum surface and installation surface;

[0036] The machining allowance distribution includes:

[0037] The amount of rough machining material removal is not less than 85%, and the rough machining allowance is 2mm;

[0038] The inner and outer shapes are finished to th...

Abstract

The invention belongs to the technical field of forging processing of plate parts, and discloses a processing method of plate structural parts, which includes: processing process design, processing allowance distribution, numerical control milling and micro boring and cutting. The invention solves the problems of deformation of parts, long processing cycle, and difficulty in guaranteeing shape and position tolerances by adding rough milling processes, artificial aging processes and rationally allocating machining allowances; the processing efficiency of products is improved by designing cutting parameters and tool path paths. and parts yield.

Description

technical field [0001] The invention relates to the technical field of forging processing of plate parts, in particular to a processing method of plate structural parts. Background technique [0002] In aerospace products, the plate structural parts used to install the control system, because the reference plane and installation surface used for assembly affect the accuracy of the control system after installation, the reference plane and installation surface involved in such structural parts, their shape and position The tolerance accuracy requirements are generally high, in which the flatness of the datum plane is required to be within 0.008mm, the flatness of the mounting surface is required to be within 0.015mm, and the perpendicularity to the datum plane is required to be within 0.025mm. [0003] The traditional manufacturing method of such structural parts mostly adopts aluminum castings for rough forming and then machining for final forming. There are problems such a...
