Name: KS3 Design and Technology : Graphics CAD CAM Torch Project Overview: In this module you will be introduced to the Design Process in order to design and make a novelty torch, complete with packaging. Beginning with hand drawn designs, you will move on to using CAD (Computer Aided Design) and CAM (Computer Aided Manufacture) in order to design and manufacture the components you need for your torch. You will analyse packaging and learn about vacuum forming in order to help you design and make a blister pack for your torch. Technical Knowledge: The Design Process Plastics Laser cutting Vacuum forming Laminating Skills: Isometric sketching using grids Shading and rendering techniques Using 2D Design (CAD) Using SketchUp (CAD) Assembly of components Evaluating Previous Level Test/20 Project Level Target Level
Brief You are to design and make a novelty torch, suitable for sale in a gift shop Specification 1. It must be a unique and original design. 2. It must be comfortable to hold and operate. 3. It must cost less than 1 to make. 4. It must have attractive packaging. Brainstorm of Ideas Torch Ideas
Plastics There are 2 classifications of plastics Thermoplastics Thermosetting Plastics These plastics are moulded by heating, and These plastics must be ground down into Glue your homework in here
Design Ideas Assessment Level 3 Level 4 Level 5 I can produce a range of designs which are sketched in isometric and rendered. I can develop a final design by considering how it I can produce a range of isometric, rendered designs. I can add notes to evaluate my ideas. I can develop and evaluate a final I can produce a range of complex, isometric, rendered designs. I can add notes to justify my ideas. I can develop and justify a final

Laser Cutting - How a Laser Tube Works Transparent mirror Solid mirror + Anode - Cathode Laser light out CO2 Gas Cold water in Hot water out A laser tube produces a very powerful beam of light which is capable of engraving and very hard materials. The laser tube is made from, and contains gas. When an electric is passed through the gas, it gives off infrared light. The light backwards and forwards between the two mirrors, getting stronger and stronger until it can pass through the mirror, and be used in the laser cutting machine. The laser tube gets very when it is used, so water is pumped through the glass tube surrounding it. The electrical contacts inside the laser tube are called. The positive + electrode is called the. The negative electrode - is called the. hot cathode cold current cutting anode electrodes glass CO2 infrared transparent bounces
Vacuum Forming 1 First a mould is made from a material such as a soft wood. The edges or sides are sloped so that it can be easily removed once the plastic has been formed. 2 3 4 5 Glue your homework in here 6 7 8 9

(use sketches and notes) Glue a photo of your finished torch and package here Assessment Level 3 Level 4 Level 5 I can produce a simple torch file using the correct colours. I can recognise and include basic information on my packaging. I can produce an accurate torch file using the correct colours. I can use shading to present important information on my packaging. I can produce a complex and detailed torch file using the correct colours. I can use detailed shading to present important information on my packaging.
