Steps in designing

1. Identifying a need an establishing a design brief
2. Researching the design brief and developing a specification
3. Generating and exploring design ideas
4. Developing a proposed solution
5. Planning for production
6. Product realisation
7. Testing and evaluation

Step 5

After choosing your proposed solution (which in our case will be task 6), you have to think about how you want to make the product:

Planning for production

Planning:

Some examples which are widely used for planning

flowcharts

manufacturing plan

sequential instructions

Marking out

Marking out is where the raw materials are drawn on to mark out the sizes from the drawings in preparation for cutting.

You always need to check the sizes afterwards.

Tools for marking out

Scriber

Tri-square

Marking gauge

Crayon

Compass

Give an example of a marking tool
you have yourself

Appropriate processes

Products all around us are made from a huge variety of materials. These materials are cut, shaped, formed, joined, fitted together, finished and tested by a large variety of machines and equipment.

Take a picture of a plastic object in your surroundings and upload it here:

Examples

- sawing

- drilling

- laminating

- vacuum forming

- line bending

- injection moulding

- bending

- blow moulding

- extrusion

Fixing and joining techniques

When making a product, the different parts need to be joined together. This can be done in two ways:

- permanently (e.g. glue, nails, screws)

- non-permanently (e.g. velcro, zipper, laces, paperclip)

Assignment 1.3.2 A

Read page 45 and 46 of the orange reader (last part of section 1.3.2) about Fixing and joining techniques.

Go to your mail and open the assignment. One example is already given. Take pictures of 4 more assembled parts (2 x permanent and 2 x non-permanent). Save the document and upload it in Teams.
