What are three major types of machining processes?

• A. Drilling, shaping, and grinding
• B. Molding, casting, and punching
• C. Turning, milling, and drilling
• D. Sawing, welding, and filing

Answer: (C)

The three major types of machining processes—turning, milling, and drilling—are fundamental to subtractive manufacturing, where material is removed from a workpiece to shape it into the desired form. Turning involves rotating the workpiece against a cutting tool to produce cylindrical parts, making it especially useful for creating items like shafts and bolts. Milling utilizes a rotating cutter to remove material from a stationary workpiece, allowing for complex shapes, flat surfaces, and slots. Drilling, on the other hand, focuses on creating round holes in a workpiece, essential for various assembly and fastening processes. These processes are integral in manufacturing because they offer precise control over dimensions and tolerances, contributing to the production of high-quality components across various industries. The combination of these machining methods allows for flexibility in production and the ability to create intricate designs that meet specific engineering requirements.
