Abstract
Aviation structural material is a kind of special material for aircraft components. This material is usually produced in nitrogen-based atmosphere to protect furnace. To ensure the production operation safety and to guarantee product quality, process monitoring technology has been paid essential attention in this field. By analyzing the heating process, details including input monitoring variables, process parameters, and data pretreatment method are determined. Then DPCA method is used to deal with problems occurred in the nitrogen-based atmosphere to protect furnace heating process. Simulation experiment based on data collected from production field is conducted. The DPCA monitoring method is verified to be effective by the experiment results, and is proved with better performance in comparison with results of MPCA.
