Questions and Answers
  • 1. 

    When using the metal lathe, safety glasses are needed when?

    • A.

      While turning pieces at high speeds

    • B.

      While turning pieces at slow speeds

    • C.

      Only when starting the machine

    • D.

      During all lathe operations

    Correct Answer
    D. During all lathe operations
    Explanation
    Safety glasses are needed during all lathe operations because there is always a risk of flying debris or metal fragments that can cause eye injuries. Whether the lathe is turning pieces at high speeds or slow speeds, there is still a potential for projectiles to be ejected from the machine. Therefore, wearing safety glasses throughout all lathe operations is necessary to protect the eyes from any potential hazards.

    A lathe machine is only used for turning metal?

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    False. A lathe machine is not only used for turning metal. It is a versatile machine that can be used for various operations such as drilling, boring, cutting, and shaping different materials including wood, plastic, and metal. It is commonly used in manufacturing and machining processes to create cylindrical shapes and symmetrical objects.

  • 3. 

    A manufacturing process, typically conducted on a lathe, whereby a visually-attractive diamond-shaped (criss-cross) pattern is cut or rolled into metal is called                  .

    • A.

      Facing

    • B.

      Knurling

    • C.

      Tapering

    • D.

      Threading

    Correct Answer
    B. Knurling
    Explanation
    Knurling is a manufacturing process conducted on a lathe where a visually-attractive diamond-shaped (criss-cross) pattern is cut or rolled into metal. This process is commonly used to improve the grip and appearance of handles, knobs, or other metal surfaces. It creates a rough texture that enhances friction and makes it easier to hold onto the object. Knurling is often used in applications where a secure grip is necessary, such as in tools, machinery, or automotive components.

    Rate this question:

  • 4. 

    While knurling, extra amounts of lubrication should be used?

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    During the knurling process, extra amounts of lubrication should be used. This is because knurling involves creating a pattern of ridges on a surface by pressing a knurling tool against it. The friction generated during this process can cause excessive heat and wear on both the knurling tool and the workpiece. By applying extra lubrication, it helps to reduce friction and heat, allowing for smoother and more efficient knurling while also prolonging the lifespan of the tool.

    Check the boxes that are correct. The lathe performes what kind of functions.

    • A.

      Sanding

    • B.

      Knurling

    • C.

      Welding

    • D.

      Cutting

    • E.

      Drilling

    • F.

      Extruding

    • G.

      Bending

    Correct Answer(s)
    A. Sanding
    B. Knurling
    D. Cutting
    E. Drilling
    Explanation
    The lathe performs the functions of sanding, knurling, cutting, and drilling. These operations are commonly carried out using a lathe machine. However, welding, extruding, and bending are not functions typically performed by a lathe.

    What two types of chucks can be used to hold material while working with the lathe?

    Correct Answer(s)
    Three and four jaw chucks
    Explanation
    Three and four jaw chucks are two types of chucks that can be used to hold material while working with a lathe. These chucks are commonly used in lathe operations to securely grip and rotate the workpiece. The three-jaw chuck is designed with three movable jaws that move simultaneously, providing a self-centering grip on the workpiece. On the other hand, the four-jaw chuck allows for independent movement of each jaw, enabling the gripping of irregularly shaped or non-centered workpieces. Both types of chucks offer versatility and stability in holding the material during lathe operations.

    You should remove all baggy clothing, jewlery and tie long hair up out of the way.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement suggests that in order to ensure safety and prevent accidents, it is advisable to remove baggy clothing and jewelry, as well as tie long hair up. This is likely because loose clothing, dangling jewelry, and untied long hair can get caught in machinery or equipment, posing a risk of injury or entanglement. Therefore, the answer "True" indicates that it is indeed important to follow these precautions for safety purposes.

    Always remove the                                       before engaging the lathe.

    • A.

      Safety guard

    • B.

      Cutting tool

    • C.

      Chuck wrench

    • D.

      Metal chips

    Correct Answer
    C. Chuck wrench
    Explanation
    The correct answer is "chuck wrench" because the sentence suggests that before engaging the lathe, something needs to be removed. Among the given options, the chuck wrench is the most logical choice as it is a tool used to tighten or loosen the chuck, which holds the workpiece in the lathe. Removing the chuck wrench ensures that it is not accidentally left inside the lathe while it is in operation, which could cause damage or injury.

    NEVER try and stop the lathe from moving with you hands.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    It is extremely dangerous to try and stop the lathe from moving with your hands. Lathes are powerful machines that rotate at high speeds, and attempting to stop them manually can result in severe injuries or even death. It is important to always follow proper safety protocols and use the appropriate tools and equipment when operating a lathe.

    Rate this question:

  • 10. 

    What safety Equipment should be used when operating the metal lathe?

    • A.

      Safety Apron

    • B.

      Shop Glass

    • C.

      Combat boots

    • D.

      None of the above

    Correct Answer
    A. Safety Apron
    Explanation
    When operating a metal lathe, it is important to wear a safety apron. This is because a metal lathe involves the use of sharp tools and rotating parts, which can pose a risk of injury. A safety apron provides protection by covering the front of the body and preventing loose clothing or debris from getting caught in the machine. It acts as a barrier against potential hazards and helps to minimize the risk of accidents or injuries while operating the metal lathe.
