A more thorough explanation:

Definition: A workpiece is the physical object or material that is being worked on or transformed in a manufacturing or production process. It is the raw material that is used to create a finished product.

Example 1: In a metalworking factory, a piece of metal that is being cut, shaped, or welded into a specific form is considered a workpiece.

Example 2: In a woodworking shop, a block of wood that is being carved, sanded, or painted to create a piece of furniture is a workpiece.

These examples illustrate how a workpiece is the starting point for a manufacturing or production process. The workpiece is transformed through various techniques and processes to create a finished product that meets specific requirements or specifications.
