Complex aircraft components such as blades have a number of production variables that need to be controlled to maximise the production throughput in a factory. These start with variances in forging process and some hidden features needing ultrasonics. This means there is a level of bespoke machining on every part. Traditionally this has been achieved with high level of manual finishing. This paper/presentation is a case study on how metrology has been integrated with robotics to give complex dimension control and maximise automated machining.
