Measurement-assisted assembly (MAA)[1] is any method of assembly in which measurements are used to guide assembly processes.
Such processes include: Measurement-assisted assembly is typically used for large structures such as aircraft and steel fabrications.
It can be used to improve production rates, reduce reworking and increase flexibility for processes where manual reworking during assembly is required to maintain assembly form and component interface conditions.
This type of approach generally offers no advantages where part-to-part interchangeability can already be achieved.
