Which milling operation removes material from the workpiece using the side of the tool?

• A. Peripheral milling
• B. End milling
• C. Slot milling
• D. Plunge milling

Answer: (A)

Peripheral milling uses the side of the cutter to remove material. As the cutter spins, the cutting edges around its circumference engage the work and shear material away while the tool advances across the surface, producing a cut that runs along the length. In contrast, end milling uses the end of the cutter to remove material (creating flats and pockets), and plunge milling involves feeding the cutter straight into the work with the tip doing the cutting. Slot milling is typically done with an end mill to create a slot, not primarily by the side of the cutter.
