The study shows how techniques approached by the 4.0 industry have the potential to contribute to manufacturing, breaking the limits imposed by the previous state of the art systems. This paper proposes a method capable of calculating an indicator for the final quality of the drilled holes, by using a committee of neural networks, which analyses data obtained by monitoring the electric current consumed by the drilling system drive. The method has the potential to enhance the efficiency of the drilling process, avoiding measurement steps and physical inspections that increases the cell cycle time.The proposal contributes to the literature by presenting an unprecedented application and to the praxis by solving a relevant problem of the aerospace industry. neural networks precision holes aircraft structures advanced manufacturing Full Text Cite Share Download PDF Status: Published Journal Publication published 25 Jul, 2023 Read the published version in The International Journal of Advanced Manufacturing Technology → Version 1 posted Reviewers agreed at journal 20 Mar, 2023 Editor assigned by journal 19 Mar, 2023 First submitted to journal 17 Mar, 2023 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
