Machining Quiz

What is the purpose of cutting tools in machining?

• The purpose of cutting tools in machining is to remove material and shape the workpiece.

• The purpose of cutting tools in machining is to hold the workpiece in place during machining.

• The purpose of cutting tools in machining is to create a smooth surface finish on the workpiece.

• The purpose of cutting tools in machining is to add material and shape the workpiece.

Name one type of cutting tool used in machining.

• hammer

• screwdriver

• paintbrush

• lathe tool

What is the difference between roughing and finishing milling operations?

• Roughing milling and finishing milling are the same operations, just performed at different speeds.

• Roughing milling removes small amounts of material quickly, while finishing milling removes large amounts of material to achieve a smooth surface finish.

• Roughing milling removes large amounts of material quickly, while finishing milling removes small amounts of material to achieve a smooth surface finish.

• Roughing milling is used for metal materials, while finishing milling is used for non-metal materials.

What is the main advantage of using a face milling cutter?

• Efficient material removal

• Increased tool life

• Smooth surface finish

• Reduced cutting forces

What is the purpose of a lathe machine in turning operations?

• The purpose of a lathe machine in turning operations is to heat and melt workpieces.

• The purpose of a lathe machine in turning operations is to create square-shaped workpieces.

• The purpose of a lathe machine in turning operations is to shape and cut cylindrical workpieces.

• The purpose of a lathe machine in turning operations is to polish and smooth workpieces.

What is the difference between facing and boring in turning operations?

• Facing is cutting a round surface, while boring is creating a flat surface.

• Facing is cutting a flat surface, while boring is enlarging or creating a hole.

• Facing is enlarging or creating a hole, while boring is cutting a flat surface.

• Facing and boring are the same thing in turning operations.

What is the purpose of a boring bar in turning operations?

• The purpose of a boring bar in turning operations is to enlarge or finish the diameter of a hole.

• The purpose of a boring bar in turning operations is to remove material from the outside of a workpiece.

• The purpose of a boring bar in turning operations is to create a flat surface.

• The purpose of a boring bar in turning operations is to reduce the diameter of a hole.

What is the difference between external and internal turning?

• External turning is used for roughing operations, while internal turning is used for finishing operations.

• External turning is performed on the inner surface of the workpiece, while internal turning is performed on the outer surface of the workpiece.

• External turning is performed on the outer surface of the workpiece, while internal turning is performed on the inner surface of the workpiece.

• External turning is a faster process compared to internal turning.

What is the purpose of a live center in turning operations?

• To provide stability and prevent vibrations during turning operations.

• To cool down the workpiece and prevent overheating during rotation.

• To hold the workpiece in place and prevent it from moving.

• To support the workpiece and reduce friction during rotation.

What is the main advantage of using a CNC machine in machining?

• Faster production time

• Automation and precision

• Lower cost

• Less skilled labor required
