Which of the following processes is not part of wasting?

In the context of engineering design, "wasting" refers to the processes that remove material from a workpiece, ultimately decreasing its size or altering its shape. Cutting, drilling, and shaping all fall under this definition as they involve the removal of material to achieve a desired form or feature.

Joining materials, on the other hand, focuses on the assembly of two or more components to create a finished product or structure. This process does not involve removing material but rather connects pieces together, maintaining their original shapes and sizes. Therefore, it does not align with the traditional understanding of wasting.

Understanding these distinctions is crucial for students as they navigate various manufacturing and design processes, helping to clarify which techniques are focused on material removal and which aim at assembly or integration.
