Question 1: Describe three different cutting tools commonly used in D&T and explain what type of materials each tool is best suited for.

Answer: A saw (e.g., hand saw or jigsaw) for cutting wood and some plastics; a craft knife (e.g., Stanley knife) for cutting paper, card, and thin plastics; scissors for paper, fabric, and thin plastics.

Question 2: Explain the importance of choosing the correct cutting blade or tool for a specific material.

Answer: Using the correct blade minimizes damage to the material, ensures a clean cut, improves safety, and increases efficiency during the cutting process.

Question 3: List two safety precautions you should take when using a cutting tool in a workshop.

Answer: Wearing safety goggles to protect eyes from debris, and ensuring the workpiece is securely clamped before cutting.

Question 4: Design Brief: You need to create a lightweight, curved piece of plastic for a model. Which cutting method would you choose and why?

Answer: A hot wire cutter would be suitable because it can easily cut and shape foam or plastics into curved forms without cracking or splintering.

Question 5: Sketch a plan for a simple jig that could help cut multiple pieces of wood to the same length. Label the main parts of your jig.

Answer: A correct sketch would show a rectangular base, adjustable stops for setting lengths, and guides for positioning the saw blade or cutting tool, with labels for each part.

Question 6: Draw a cross-section of a hand saw blade and label the key features, including the teeth, body, and handle attachment.

Answer: A sketch should depict a narrow, elongated blade with teeth along one edge, a handle attached at one end, and the blade's body connecting the teeth and handle. Labels should identify 'teeth', 'blade body', and 'handle'.

Question 7: Explain the difference between cross-cutting and ripping when using a saw.

Answer: Cross-cutting involves cutting across the grain of the wood, producing a smooth end; ripping involves cutting along the grain to make the wood narrower or to cut it to length.

Question 8: Identify two common problems that can occur when cutting materials and suggest how to prevent them.

Answer: Splintering—prevent by using a sharp blade and scoring the cut line beforehand; uneven cuts—prevent by securely clamping the workpiece and using a guide or fence.

Question 9: Design Brief: You are making a decorative box from thin plywood. Describe how you would ensure precise cuts for the box sides. Include any tools or techniques you would use.

Answer: Use a straight edge or metal ruler as a guide, clamp the workpiece securely, and use a fine-tooth saw or a track saw for straight, accurate cuts. Mark measurements carefully before cutting.

Question 10: Sketch a detailed plan for a safe working area dedicated to cutting activities. Include at least three key features or safety considerations.

Answer: A large, clear workspace with a stable cutting surface, safety equipment such as goggles and gloves, appropriate storage for tools, and clear signage or markings for safe tool use.
