What is the purpose of using masking tape during the preparation of the tool?

Using masking tape during the preparation of the tool primarily serves to protect the tool from damage. In the aerospace assembly process, tools are often exposed to various substances, including chemicals, adhesives, and composite materials that can cause wear, corrosion, or contamination. Applying masking tape creates a protective barrier that helps prevent these materials from adhering to or scratching the tool's surface. This is particularly important in aerospace applications where precision and the integrity of tools significantly impact the quality of the assembly process.

While marking measurements and enhancing visibility are beneficial practices, they are secondary to the primary protective function of masking tape. Similarly, securing composite material is not the main intent of using masking tape; specific securing methods are employed for that purpose. Thus, masking tape's role in safeguarding the tools is crucial in maintaining their performance and longevity in the aerospace manufacturing environment.
