Workpiece → It is formed from "work" (from Old English *weorc*, meaning activity or labor) and "piece" (from Old French *piece*, meaning a part or fragment). The word "workpiece" refers to a piece of material that is being worked on or shaped in a manufacturing process.
Think of 'work' as the activity being done and 'piece' as a part of something — a workpiece is simply a part that is being worked on.
