Question 1: Define CAD and explain its primary purpose in the design process.

Answer: CAD, or Computer-Aided Design, is software used to create detailed 2D or 3D models of products. Its primary purpose is to facilitate precise design development, modification, and visualization before manufacturing.

Question 2: Describe two advantages of using CAD over traditional hand-drawing methods.

Answer: Advantages include increased accuracy and precision in designs, and the ability to easily modify and update models without starting from scratch.

Question 3: Explain what CAM is and how it integrates with CAD in a manufacturing process.

Answer: CAM, or Computer-Aided Manufacturing, uses software to control manufacturing equipment based on CAD models. It automates production, ensuring designs are accurately transformed into physical products.

Question 4: Identify three types of manufacturing processes that can be controlled by CAM systems.

Answer: Three processes include CNC milling, laser cutting, and 3D printing.

Question 5: Describe a scenario where CAD/CAM would be particularly beneficial for producing a complex product.

Answer: CAD/CAM is beneficial when manufacturing complex, detailed components like custom jewellery or intricate electronic housings, as it allows precise design and automated production with minimal manual intervention.

Question 6: Sketch a simple design of a product that could be created using CAD and manufactured with CAM. Label key features of your design.

Answer: A clear sketch of a small box with labeled dimensions, lid, hinges, and possibly a handle. The sketch should emphasize clean lines, precise features, and accessibility for manufacturing.

Question 7: Sketch a flow diagram showing the typical steps in a CAD/CAM project from initial idea to finished product.

Answer: A flow diagram with stages including: 1. Concept/Idea, 2. CAD Design, 3. CAD Review/Modification, 4. CAM Programming, 5. Manufacturing, 6. Assembly/Finishing.

Question 8: [WORKSHOP TASK] Imagine you need to produce 50 identical plastic components. Outline how CAD and CAM would be used to complete this task efficiently.

Answer: Design the component in CAD, then use CAM software to generate toolpaths for automated manufacturing (e.g., CNC machine or 3D printer), ensuring consistent quality and efficient production of all parts.

Question 9: Identify two potential challenges or limitations of using CAD/CAM in manufacturing.

Answer: Challenges include high initial setup costs and the need for skilled operators to program and maintain the software and machinery.

Question 10: Suggest two safety considerations when working with CAM machinery during manufacturing.

Answer: Safety considerations include wearing appropriate personal protective equipment (PPE) and ensuring machinery is properly maintained and guarded to prevent accidents.
