Abstract

The embodiment of the invention provides a method for machining a metal sheet and a milling machine. The metal sheet comprises a front surface, a back surface, a side surface and a through hole located in the center of the metal sheet, wherein a groove is formed around the through hole; a plurality of special-shaped slots are formed in the front surface; and a reinforcement structure is arranged on the back surface. The method comprises the steps of roughly milling the front surface, the back surface, the side surface and the through hole, performing semi-finish milling on the side surface ofthe metal sheet, turning over the metal sheet many times, performing semi-finish milling on the groove around the through hole, the special-shaped slots in the front surface and the reinforcement structure on the back surface, turning over the metal sheet many times, and performing finish milling on the groove around the through hole, the special-shaped slots on the front surface and the reinforcement structure on the back surface. According to the machining method, residual stress on the surface and in the metal sheet can be effectively controlled; a deformation error of the metal sheet due to stress release is reduced; and the machining precision is guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for processing sheet metal parts and a milling machine. Background technique [0002] Residual stress refers to the stress that exists inside an object and maintains its own balance when there is no external force or external moment. Inhomogeneous plastic deformation caused by external force or temperature change is the main cause of residual stress. In the process of producing, processing or processing materials, due to uneven plastic deformation in local areas of materials, residual stress will inevitably occur. Before cutting, the internal residual stress of the part is in a state of self-balance. During the cutting process, the processed material is gradually removed, the residual stress in the cutting layer is gradually released, the stiffness of the workpiece itself changes accordingly, the initial stress balance state inside the part is broken, and the part c...
