Final answer:
Reaming is a process used in metalworking to smooth or enlarge existing holes. It involves using a tool called a reamer to remove a small amount of material from the hole's surface, resulting in a smoother and more accurate hole.
Step-by-step explanation:
The process designed to smooth or enlarge existing holes, often used in metalworking, is called reaming.
Reaming is a machining operation that involves a tool called a reamer, which has multiple cutting edges. The reamer is used to remove a small amount of material from the hole's surface, resulting in a smoother and more accurate hole.
For example, when a hole in a metal block is drilled slightly smaller than the desired size, reaming is used to precisely enlarge the hole to the required dimensions. Reaming ensures tight tolerances and smooth surfaces in the hole, allowing for better fitting and functionality of components.
