Abstract

The invention belongs to the technical field of plate part forging machining and discloses a plate-type structural component machining method. The plate-type structural component machining method comprises the steps of machining technology process design, machining allowance distribution, numerical control milling and microscale bore cutting. According to the plate-type structural component machining method, through the addition of a rough milling procedure and an artificial ageing procedure and the reasonable distribution of machining allowances, the problems that the parts are deformed, the machining period is long and the form and location tolerance is difficult to be guaranteed are solved; through the design of cutting parameters and a tool path route, the machining efficiency of products and the yield of the parts are improved.

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...
