Question 1: Describe a scenario where a piece of timber needs to be shaped into a specific form for a furniture component. Which shaping process would be most appropriate and why?

Answer: A suitable process might be routing or sanding, depending on the detail required. Routing is used for creating grooves or complex profiles, while sanding smooths surfaces. The choice depends on the shape complexity and desired finish.

Question 2: Explain the purpose of using a jigsaw in shaping wood. What are the advantages of this tool?

Answer: A jigsaw is used for cutting curves and intricate shapes in wood. Its advantages include versatility, ability to cut complex patterns, and ease of use for detailed work.

Question 3: Identify and describe two different shaping techniques suitable for metal work.

Answer: Two techniques are: (1) Forging, which involves heating metal and hammering it into shape, and (2) Casting, which involves pouring molten metal into a mold to obtain the desired shape.

Question 4: Sketch a simple plan for shaping a piece of plastic to create a rounded edge for a product. Label the key stages or tools involved.

Answer: A correct sketch would show a plastic piece secured in a vice, with a rounded file or sanding tool being used to smooth the edge. Labels might include 'clamp', 'filing tool', and 'rounded edge'.

Question 5: Design a process for shaping a large sheet of sheet metal into a curved form suitable for an automotive panel. Outline the steps involved.

Answer: Steps include: (1) Marking the desired curve on the sheet, (2) Clamping the sheet securely, (3) Using a forming brake or hammering over a form to bend the sheet gradually, (4) Applying heat if necessary to assist bending, (5) Finishing with smoothing tools.

Question 6: Create a detailed sketch plan for shaping a wooden chair leg with a tapered profile. Include the tools and methods you would use.

Answer: A plan should depict a block of wood with marked tapers, showing use of a spokeshave or drawknife to remove material gradually, possibly with a sanding block for smoothness. Labels include 'marking gauge', 'spokeshave', and 'sanding block'.

Question 7: What safety precautions should be taken when using a power sander for shaping wood?

Answer: Safety precautions include wearing safety glasses, using dust extraction or wearing a mask to avoid inhaling dust, securing the workpiece firmly, and keeping hands away from moving parts.

Question 8: Compare the shaping of a soft material, like foam, with a hard material, like metal. What techniques and tools are suitable for each?

Answer: Foam can be shaped using hot wire cutters or knives, which are quick and precise. Metal requires cutting tools like saws, files, or abrasive wheels, and often involves more force or heat for shaping.

Question 9: Explain how the choice of shaping process can affect the final quality and durability of a product.

Answer: The shaping process influences surface finish, accuracy, and strength. For example, poorly executed shaping may lead to weak points or rough surfaces that affect durability and aesthetic quality.

Question 10: Identify a shaping process suitable for producing detailed and delicate metal components and justify your choice.

Answer: Casting or precision machining are suitable. Casting allows intricate designs to be formed, while machining can produce detailed and precise features on metal components.
