What is the status of layout tape around the holes before deburring?

The correct answer addresses the importance of maintaining the integrity of the holes during the deburring process. When preparing parts for assembly, particularly in aerospace applications, the layout tape serves a specific purpose: it protects the surfaces around the holes from damage, contamination, and premature wear during the deburring process.

Removing the layout tape before deburring is essential because it allows for a clear and unobstructed view of the holes. This ensures that the mechanic can effectively and accurately deburr the edges around each hole, which is critical for achieving the proper fit, reducing the risk of stress concentrations, and ensuring the structural integrity of the assembly. If the tape were left intact, it could interfere with the deburring process, potentially leading to incomplete work or misunderstandings regarding the position and condition of the holes.

Choice must be made to remove the layout tape entirely before commencing with deburring to ensure the process is both thorough and effective. Properly preparing the component by removing any unnecessary tape helps maintain the quality and reliability standards necessary in aerospace manufacturing.
