A Blending Control Aircraft Assembly Quality Method Using Key Assembly Characteristic
Assembly quality control is the main problem concerned by assembly departments in aircraft industry. This paper discusses the key assembly characteristics (KACs) which are the critical dimension characteristics for assembly quality in details, and then proposes a mathematical method which consists of identification and blending control method (BCM) towards KACs. BCM includes tightening tolerance and compensation, which can quantitatively control the KACs determined by validating error stack-up. A demonstration is given to verify the validity of the proposed method by controlling the assembly quality of an aircraft vertical tail.
