Problems solved by technology

In the continuous process of the existing processing process, the integral machine-added wallboard products rely on multiple allowance removal, cavity opening processing, layered processing and tooling clamping and positioning, and the internal stress of the material and the processing stress of the traditional processing scheme are not fully released. , the maximum deformation (warping, torsion, etc.) cannot occur in a short time, but after a period of time, the residual stress will be released, the state of the parts will have a large deformation, and there will be a large stress in the assembly state, which will affect the quality of aviation products

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method for integral wall board parts. Background technique [0002] One-sided surface, one-sided structural form of integral machine plus wall panel parts is one of the important structures used in aircraft development, and is mostly used in key parts such as aircraft wings. Due to the large size of large wall panels, the machining removal rate is very high (95% material removal rate), and it is very important to control the deformation during machining. In the continuous process of the existing processing process, the integral machine-added wallboard products rely on multiple allowance removal, cavity opening processing, layered processing and tooling clamping and positioning, and the internal stress of the material and the processing stress of the traditional processing scheme are not fully released. , the maximum deformation (warping, to...
