  1. A drawing note specifying 'REMOVE ALL BURRS AND SHARP EDGES' applies to which manufacturing concern?

    Answer: Post-machining surface cleanup

    This note directs machinists to deburr all edges after cutting or machining to ensure safety and proper fit.

  2. What does 'cold working' do to the mechanical properties of a metal?

    Answer: Increases strength and hardness while decreasing ductility

    Cold working (plastic deformation below recrystallization temperature) introduces dislocations that increase strength and hardness but reduce ductility.

  3. Which standard body publishes material specifications such as A108, A36, and A514 for carbon and alloy steels?

    Answer: ASTM International

    ASTM International publishes the widely used A-series specifications for ferrous materials used in manufacturing and construction.

  4. What is the purpose of annealing a metal part?

    Answer: To relieve internal stresses and improve ductility

    Annealing heats metal to a controlled temperature and cools it slowly to eliminate internal stresses and restore ductility.

  5. Which of the following best describes the extrusion manufacturing process?

    Answer: Forcing material through a shaped die to create a continuous profile

    Extrusion pushes or pulls material through a die opening to produce parts with a constant cross-section along their length.

  6. A drafter must specify a corrosion-resistant coating for a steel part used outdoors. Which specification is commonly called out on the drawing?

    Answer: Hot-dip galvanizing per ASTM A123

    ASTM A123 covers hot-dip galvanized zinc coatings on steel, providing excellent corrosion protection for outdoor applications.
