Final answer:
The term pegging is incorrectly defined in the student's question; it's a supply chain management term that refers to linking demand to supply, not identifying parent items. Precision engineering is used for fitting a metal peg tightly in a metal block.
Step-by-step explanation:
The term pegging does not refer to identifying the parent items that have generated a given set of material requirements for a part or subassembly. That statement is false. Pegging in the context of manufacturing and supply chain management is commonly used to describe the process of linking (or pegging) a specific inventory demand to supply, so that firms can trace why the material was required. For a tight fit of a metal peg in a hole in a metal block, precision engineering techniques such as machining to exact tolerances or the use of heating or cooling to expand or contract parts during assembly are often applied.
