Which manufacturing operation uses a lathe to turn material?

• A. Milling
• B. Turning
• C. Casting
• D. Finishing

Answer: (B)

Turning is the operation that uses a lathe to rotate the workpiece while a cutting tool removes material to shape it. The lathe holds the part in a chuck or between centers and spins it, so the tool can create cylindrical or conical features—such as shafts, pins, or threads—by moving along or across the rotating workpiece. This rotational setup is what defines turning. In contrast, milling uses a rotating cutter to remove material from a stationary workpiece, casting involves pouring molten material into a mold, and finishing refers to final surface treatment or polishing. So the process that specifically uses a lathe to turn material is turning.
