Which operation would NOT be included in holemaking?

Holemaking refers specifically to operations that create or refine holes in a workpiece. Processes commonly associated with holemaking include drilling, boring, and tapping.

Drilling is the initial process where a hole is created using a rotating drill bit. Boring follows, which is used to enlarge or finish an existing hole to achieve a more precise diameter and improve surface finish. Tapping is another critical operation in holemaking that involves creating internal threads within the hole for fastening purposes.

Grooving, on the other hand, involves creating a groove or channel on the surface of a material, which is not related to forming holes. Since grooving focuses on shaping the exterior of the workpiece rather than making or refining holes, it is not considered a holemaking operation. Therefore, it correctly identifies the operation that would not be included in holemaking.
