Welcome to Design Technology 2
This is a full year class where you continue to develop the design and make skills that you learned in Design Technology 1. This course focuses mostly on working with metal and you will learn how to use a vast array of metal processing tools and machines such as oxyacetylene cutting, brazing and welding, MIG welding, Plasma cutting, metal turning, grinding etc.
In this Unit you will learn the following:
- How to Select, Mark Out and Prepare Materials
- How to Cut and Shape different types of stock metal
- How to MIG/GMAW weld Tacks, Beads, Butt joints, Fillet joints and Lap joints
- How to finish the metal after cutting or joining
In order to start the summative assessment for this unit, I need to first teach you how to safely operate in the workshop, and use the metalworking tools and machines.
I will teach you in detail about how to be safe in the workshop and about a range of skills and techniques. You will then you will get to practice until you can demonstrate proficiency with these skills and techniques. The skills and techniques that you will be formatively assessed on are:
- Selecting, Marking out and Preparing Materials
- Cutting & Shaping (Hacksaws, Chop saw, Plasma cutter)
- MIG/GMAW Welding (Tacks, Beads, Butt Joints, Fillet Joints, Lap Joints)
- Finishing (Filing, Angle Grinding, Using Abrasives & Spray Painting)
Please see the following attachment for the formative & summative assessment rubric for this unit: Formative & Summative Assessment Rubric
In groups of 2 to 3, use the metal working skills that you have learned to produce one of the following:
- Vice Stand,
- Angle Grinder holder/stand (for 4 angle grinders)
- 75Kg Anvil Stand
- Slow Speed Grinder Table
- MIG gun holster & magnetic Plasma cutting fence
- Research existing product and create a Pinterest board for this research,
- Gather necessary measurements needed to make the product (e.g. If making an Anvil stand you need to know the size of the anvil & anthropometric data for appropriate height it should be at)
- Research what materials are currently available in the metal storage cage - your ideas needed to be based from what materials are available
2. Initial Ideas
Sketch 4 ideas for your solution to the problem - include the following for each design:
- Sketch(es) of each idea to clearly show how it will work
- Estimated measurements, size and thicknesses of materials,
- Written annotations/labels to explain idea
- Written description of how you idea will work
3. Design Development
Create a CAD rendering and orthographic projection of your final design. Draw it exactly as how it will be made - I need to see the following in your design:
- Types of joints used
- Type and thickness of the metal used
- Location of any holes needed to bolt down the vice/grinders/anvil etc
- Specific measurements of each part needed to make the product
Produce a Gantt chart detailing all the steps/processes that you will need to follow in order to complete your project. Try to then divide up these steps so that every member of your team has an equal work load and can be 'on task' throughout the project. The deadline for this project is written on the board - please make sure that you allow for enough 'slack' in your gantt chart to allow you to complete the project by this date.
Refer to you gantt chart and start working on the tasks needed to complete your project, I will be watching carefully to make sure that you:
- Understand your design and can read your orthographic projection,
- Can accurately mark out and cut the necessary materials,
- Can prepare and set up the materials accurately and ready for processing
- Can MIG weld with accuracy and consistency
- Can skilfully use the angle grinders to prepare the material for painting
- Can spray paint consistently without getting imperfections in the surface/coat.
6. Test & Evaluate
Now that your product is finished, it is time to test and evaluate it in use. Does the product function as desired? Is it an appropriate height/width for use? Are there any dangerous parts/sharp edges? The reflection is an important part of the design process as it allow you to think about what you have learned and how you would do things differently in the future if faced with similar design problems.
Your written evaluation should include the following information:
- Photographs of the end product and in use
- A written description that details:
- What you have made and why
- What you have learned in process of making the product
- How did you find collaborating with others?
- What new things did you learn?
- If a student was starting this project for the first time, what recommendations would you make to help them?
- What did you find challenging in this project? How did you overcome these challenges?
- What are you proud of? What was your biggest achievement in this project?
- What feedback have you received about this product?
- If you had unlimited resources, how would you change your design?
- Any other information that should be included in your evaluation.
