Abstract

A manufacturing system for producing airplane structural components, including a drilling unit for producing bores in a material assembly made of at least two material plies for the purposes of inserting fastening elements and having a measuring unit for ascertaining geometry parameters for a previously produced bore. The measuring unit includes measuring electronics with an optical sensor element, a measuring optical unit and a measuring lance. The measuring unit produces an optical measurement beam that emerges from the measuring lance via the measuring optical unit and that is incident on a measurement point on the respective bore inner surface. A measurement movement between measuring lance and material assembly is provided in a measurement cycle and the measuring unit cyclically ascertains distance values to various measurement points at a scanning rate during the measurement movement and ascertains at least one geometry parameter for the respective bore from the distance values.
