Which term refers to the group of manufacturing operations that include drilling, turning, milling, and grinding?

• A. Machine Processes
• B. Casting
• C. Welding
• D. Finishing

Answer: (A)

Drilling, turning, milling, and grinding are classic examples of machining—the group of processes that remove material using machine tools to shape a workpiece. These operations rely on cutting or abrasive action to form the desired geometry, size, and surface finish. Casting, welding, and finishing are different kinds of manufacturing activities: casting forms shape by pouring material into a mold; welding joins parts together; finishing covers surface treatments after the primary shaping. Since the listed operations all involve material removal with machine tools, they fall under machine processes (machining).
