Which of the following is NOT a common manufacturing process?

  1. Casting

  2. Welding

  3. Machining

  4. 3D Printing


Correct Option: D
Explanation:

3D Printing, also known as Additive Manufacturing, is a relatively new manufacturing process that involves building a product by adding material layer by layer.

What is the purpose of a jig in manufacturing?

  1. To hold and guide a workpiece during machining.

  2. To measure the dimensions of a workpiece.

  3. To apply force to a workpiece.

  4. To inspect the quality of a workpiece.


Correct Option: A
Explanation:

A jig is a tool that holds and guides a workpiece during machining operations to ensure accuracy and repeatability.

Which of the following is a common material used in casting?

  1. Steel

  2. Aluminum

  3. Plastic

  4. Wood


Correct Option: B
Explanation:

Aluminum is commonly used in casting due to its low melting point, good castability, and high strength-to-weight ratio.

What is the primary purpose of a cutting tool in machining?

  1. To remove material from a workpiece.

  2. To shape a workpiece.

  3. To measure the dimensions of a workpiece.

  4. To hold a workpiece in place.


Correct Option: A
Explanation:

The primary purpose of a cutting tool in machining is to remove material from a workpiece to achieve the desired shape and dimensions.

Which of the following is a common type of welding process?

  1. Arc Welding

  2. Resistance Welding

  3. Solid-State Welding

  4. Brazing


Correct Option: A
Explanation:

Arc Welding is a widely used welding process that involves melting the edges of two metal pieces using an electric arc.

What is the primary purpose of a fixture in manufacturing?

  1. To hold and position a workpiece during assembly.

  2. To measure the dimensions of a workpiece.

  3. To apply force to a workpiece.

  4. To inspect the quality of a workpiece.


Correct Option: A
Explanation:

A fixture is a tool that holds and positions a workpiece during assembly operations to ensure accuracy and repeatability.

Which of the following is a common type of plastic used in injection molding?

  1. Polyethylene (PE)

  2. Polypropylene (PP)

  3. Polyvinyl Chloride (PVC)

  4. Polystyrene (PS)


Correct Option: B
Explanation:

Polypropylene (PP) is a commonly used plastic in injection molding due to its high strength, toughness, and resistance to chemicals.

What is the primary purpose of a lathe in machining?

  1. To turn a cylindrical workpiece.

  2. To mill a flat surface.

  3. To drill a hole.

  4. To grind a surface.


Correct Option: A
Explanation:

A lathe is a machine tool used to turn a cylindrical workpiece by rotating it while a cutting tool removes material to achieve the desired shape and dimensions.

Which of the following is a common type of metalworking fluid used in machining?

  1. Water-Soluble Oil

  2. Synthetic Oil

  3. Mineral Oil

  4. Solid Lubricant


Correct Option: A
Explanation:

Water-Soluble Oil is a commonly used metalworking fluid in machining due to its cooling and lubricating properties, as well as its ability to prevent corrosion.

What is the primary purpose of a milling machine in machining?

  1. To turn a cylindrical workpiece.

  2. To mill a flat surface.

  3. To drill a hole.

  4. To grind a surface.


Correct Option: B
Explanation:

A milling machine is a machine tool used to mill a flat surface on a workpiece by rotating a cutting tool and moving the workpiece against it.

Which of the following is a common type of abrasive used in grinding?

  1. Aluminum Oxide

  2. Silicon Carbide

  3. Diamond

  4. Cubic Boron Nitride


Correct Option: A
Explanation:

Aluminum Oxide is a commonly used abrasive in grinding due to its hardness, toughness, and relatively low cost.

What is the primary purpose of a drill press in machining?

  1. To turn a cylindrical workpiece.

  2. To mill a flat surface.

  3. To drill a hole.

  4. To grind a surface.


Correct Option: C
Explanation:

A drill press is a machine tool used to drill a hole in a workpiece by rotating a cutting tool and applying downward pressure.

Which of the following is a common type of non-destructive testing (NDT) method?

  1. Ultrasonic Testing

  2. Radiography

  3. Magnetic Particle Inspection

  4. Dye Penetrant Inspection


Correct Option: A
Explanation:

Ultrasonic Testing is a common NDT method that uses high-frequency sound waves to detect flaws and defects in materials and components.

What is the primary purpose of a grinder in machining?

  1. To turn a cylindrical workpiece.

  2. To mill a flat surface.

  3. To drill a hole.

  4. To grind a surface.


Correct Option: D
Explanation:

A grinder is a machine tool used to grind a surface on a workpiece by rotating an abrasive wheel and moving the workpiece against it.
