Research on Key Process Quality Control of Spacecraft Composite Material Products
In view of the complex system of spacecraft composite material products,the difficulty of research and development technology,high cost,and the production mode of multiple varieties and small batches,the number of samples that can be used for key process identification is too small.In order to solve the limitations of hierarchical decomposition method for key process iden-tification and statistical process control technology for process quality control,the key process identification idea of spacecraft composite material products is put forward,the key process iden-tification index system is established,and the calculation method of the quantitative value of the index is specified.By using cause-and-effect diagram method,the factors affecting the quality of key processes are analyzed one by one from six aspects of man,machine,material,method,en-vironment and measurement,and the quality control measures for the design process review,process scheme design,tooling design,process specification design,process implementation,process inspection,finished product inspection and information feedback application are clearly defined.The above measures are applied to the development of a spacecraft composite material load adaptation structure.All the key/important characteristics of the products are effectively controlled,and the quality control and management requirements based on prevention are rea-lized.The research results can provide reference for the process quality control of spacecraft ma-nufacturing.
