What is the purpose of the layout tape when covering the scrap part?

The primary purpose of layout tape when covering the scrap part is to cover the entire surface. This action protects the piece from potential damage during handling and transportation, ensuring that any work done on the piece is preserved and that it remains free from debris, scratches, or other marks that could affect quality. By covering the entire surface, layout tape also helps to provide a clean, neat workspace, which is vital in maintaining quality standards in aerospace assembly and manufacturing.

Additionally, layout tape often serves to delineate areas for cutting, drilling, or other operations, making it easier to visualize the working regions on the material. While layout tape could potentially assist in highlighting specific areas or preventing scratches, its fundamental role in this context is to provide complete coverage of the scrap part.
