The dimensional accuracy of aviation forgings is very important, which is directly related to the safety and performance of aircraft. The following are some methods of dimensional accuracy control for aviation forgings: Design control: In the design stage, it is necessary to accurately define the dimensional requirements of the forgings, and take into account the deformation and shrinkage of the forgings to determine the appropriate dimensional tolerance range. Material selection: Select alloy materials with good machinability and stability to reduce the size change of forgings in forging and subsequent processing. Process control: In the forging process, it is necessary to use the appropriate process parameters, such as forging pressure, temperature, etc., to control the dimensional error of the forging. In addition, it is also necessary to ensure uniform deformation and sufficient filling to avoid defects and uneven dimensional changes. Subsequent heat treatment: Aviation forgings usually require subsequent heat treatment, such as aging treatment, quenching, etc., to adjust the size of the forgings and make it meet the design requirements. Processing control: In the subsequent processing of forgings, such as CNC machining, grinding, etc., it is necessary to strictly control the processing parameters, and adopt the appropriate measurement technology to ensure the accuracy and consistency of the size. In short, the dimensional accuracy control of aviation forgings needs to be comprehensively considered and controlled from many aspects such as design, material selection, process control, heat treatment and processing to ensure that the forgings can meet the performance and safety requirements of the aircraft.
