ABSTRACT
A
utomated Fiber Placement (AFP) has become a standard manufacturing technique in the creation of
large scale composite structures due to its high production rates. However, the associated rapid layup
that accompanies AFP manufacturing has a tendency to induce defects. We forward an inspection system
that utilizes machine learning (ML) algorithms to locate and characterize defects from profilometry scans
coupled with a data storage system and a user interface (UI) that allows for informed manufacturing. A Keyence LJ-7080 blue light profilometer is used for fast 2D height profiling. After scans are collected, they are
process by ML algorithms, displayed to an operator through the UI, and stored in a database. The overall goal
of the inspection system is to add an additional tool for AFP manufacturing. Traditional AFP inspection is done
manually adding to manufacturing time and being subject to inspector errors or fatigue. For large parts, the
inspection process can be cumbersome. The proposed inspection system has the capability of accelerating
this process while still keeping a human inspector integrated and in control. This allows for the rapid capability
of the automated inspection software and the robustness of a human checking for defects that the system
either missed or misclassified.
