| In order to break the limitation of traditional measurement guarantee that only focus on the accuracy of
measuring equipment rather than the reliability of measurement results, a measurement process control management
system suitable for the full link of civil aviation engines has been constructed. The system is designed to improve the
quality of measurement data, covering the entire product measurement processes from component design to overall test,
from airworthiness certification to customer delivery. In the measurement process design stage, according to the
measurement requirements and the degree of importance of the process, the measurement capacity is analyzed, and the
measurement quality requirements, namely measurement uncertainty, are derived. In the measurement process control
stage, according to the results of uncertainty analysis, the sources of uncertainty are identified, and the measurement
process is monitored by means of measurement system analysis (MSA), control chart, and measurement capability audit.
In the measurement validity verification stage, combined with the characteristics of aero?engine measurement process in
scientific research stage, a same family measurement process collection is established, and quality verification is achieved through the measurement uncertainty evaluation. The system was initially applied to the measurement classification,
capability analysis, process monitoring and result verification of the project "high?pressure compressor rotor assembly"
during the assembly execution process in the factory, which has a reference significance for establishing the measurement
process management of all relevant parties in the process including test verification and manufacturing. |
