Abstract In the new development stage of aircraft, there may be phenomenons that the edge distance of connecting
hole doesn’t conform to the specification requirements and that connecting hole appears into parts’ R area in the engineering
data set which provided by the design department. Through the edge distance detection can check the defects of the
edge distance of connecting hole, so this rapid detection of edge distance is an important problem. The algorithm of the extraction
and rapid detection minimum distance is put forward and a quick detection software that detects the minimal hole
edge distance in the skin edge by using the CAA/CATIA platform is developed. The software can quickly screen the connecting
hole which is in inconformity to requirement, and then label this hole. The method reduces the waste in the aircraft
manufacturing process and improves the production efficiency.
