Computer Aided Manufacture

Crank Handle

A crank is an arm attached at a right angle to a rotating shaft by which reciprocating motion is imparted to or received from the shaft.

Plywood

A type of strong thin wooden board consisting of two or more layers glued and pressed together with the direction of the grain alternating.

Axel

A rod or spindle (either fixed or rotating) passing through the centre of a system.

Rebate Butt Joint

The rebate joint is a very similar woodwork joint to the butt joint but the big difference between the two is that one of the ends of the timber has a groove cut out of it to create much better holding strength.

Dowel Joint

Dowel joint. Dowels are round wooden pins of small diameter used to strengthen (reinforce) a joint. They can be bought ready made and can be used instead of nails or screws.

Pear cam

A simple toy controlled by a cam and follower. As the cam continues to rotate the arm begins to rise. The cam shown is a pear shaped cam (named after its shape).

Snail cam

Snail Cams are a particular type of Radial Cam and can be used to drive punches, hammers, automata, or drum sticks in mechanical fairground organs - or any circumstance when a sudden drop is required.

Comb joint

A finger joint, also known as a comb joint, is a woodworking joint made by cutting a set of complementary, interlocking profiles in two pieces of wood, which are then glued.

Cam follower

The part of a machine in sliding or rolling contact with a rotating cam and given motion by it.

Rotary motion

Rotary motion, also referred to as rotational motion or circular motion, is physical motion that happens when an object rotates or spins on an axis. This type of motion is analysed in much the same way as linear motion.

Oscillating motion

Oscillatory motion can be termed as the repeated motion in which an object repeats the same movement over and over.

Develop the individual:

Use of tools in a workshop is a different environment for students to work in with health and safety elements to consider. Develops the students understanding of various materials and how successful they may be with particular tools and finishes. Students create a project based on their own designs and interests so can develop confidence with their peers and shares their own beliefs and hobbies.

Create a supportive community:

supporting each other with health and safety using tools and materials in workshop. Students can guide one an another with tips and teach each other how to use tools if some students have more abilities than others. Tables are set in 4's so can work as teams, using each other strengths to create a toy that is successful.

Term 2: Completion of mini tool box

• Manufacture of product.

• Health and safety of tools and equipment in the workshop.

• Applying finishes and decorative techniques.

• Evaluation and testing.

Materials and the 6R's.

Once every 2/4 weeks on specific pieces of design process and making.

end of unit assessment.

Varnish

Resin dissolved in a liquid for applying on wood, metal, or other materials to form a hard, clear, shiny surface when dry.

Wood stain

A commercially produced substance for colouring wood.

Sanding

Smooth or polish with sandpaper or a mechanical sander.

Evaluation

The making of a judgement about the amount, number, or value of something; assessment. Specifically looking at WW and EBI with feedback from the customer.

Improvements

A thing that makes something better or is better than something else. Drawings can show a new version of the design to suggest areas of weakness that need to be improved.

Function

How a product works.

Testing

Go through a series of tests such as weight, and strength to see how successful the product is made and constructed.

Develop the individual:

Helps students to understand materials and finishes with those materials, students reflect on their success and what needs to be developed or improved in the next project based on what they have learnt this time. Students can accept constructive criticism and take on board improvements from a client. Gives students confidence.

Create a supportive community:

Students are encouraged to share ideas and ways of improving their products in order to develop them and their confidence, this can be done in class or with feedback from home developing their social skills. Students are encouraged to swap projects and use peer assessment as feedback giving a mark out of 20 for the making with reasoning for their choices.

Term 3: MP3 Amp

Research into sustainability, recycling and product life cycle.

• Building electronic circuits, understanding their needs and names.

• Manufacture of a whole product.

• Use of recycled elements for housing electronics.

• Create a wrap as a decorative finish for the product.

Once every 2/4 weeks on specific pieces of design process and making.

Solder

a low-melting alloy, used for joining less fusible metals.

Soldering Iron

An electrical tool used for melting solder and applying it to metals that are to be joined.

Switch

Turns the circuit on and off.

6 R's

The 6 Rs - Sustainability and Recycling. Recycle, Rethink, Refuse, Reuse, Repair and Reduce.

housing

Creates a home for the circuit board and speaker to sit in to display.

Graphics wrap

Creates a finish to the surface of the housing that is interesting and appealing to the client.

MP3 speaker

An MP3 player with built-in speaker is a helpful product to have if you want to be able to listen to music while on the go. These compact devices play many different types of sound files.

Electronics

The branch of physics and technology concerned with the design of circuits using transistors and microchips, and with the behaviour and movement of electrons.

Component

A part or element of a larger whole, especially a part of a machine or vehicle.

Develop the individual:

Students will work in teams to complete the electronics sections whilst other students create the wrap, students will have to take responsibility for their working environment and what stage of the design process they are at from one lesson to the next. Helps their organisation skills and confidence in time management.

Create a supportive community:

Students will work in teams to complete the electronics sections whilst other students create the wrap, they will need to support each other and play to their strengths and help others with their weaknesses.

• Write an evaluation and complete testing of product.

Once every 2/4 weeks on specific pieces of design process and making.

Client

The person you are making the product for. Specific to their needs.

recycling

Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products.

Sustainability

Avoidance of the depletion of natural resources in order to maintain an ecological balance.

Craft knife

A craft knife is most commonly used for art and craft projects. It is ideal for cutting out intricate and detailed shapes due to its sharp, thin blade. It can also be used to cut small or delicate materials accurately, without causing any damage.

Cutting mat

For every project where you use either a utility knife or a rotary cutter, you also need a cutting mat. They protect the work surface from damage, and prevent your knife blade from dulling quickly.

Graphics

The products of the graphic arts, creates signage, promotion or displays.

Reuse

Use again or more than once to help prevent waste.

Refuse

Refuse to buy or use a product based on the packaging or materials used as they are not sustainable for the environment.

Repair

Fix a product that may be broken instead of buying a new one if you can.

Reduce

To recreate a product or packaging to use less materials, production methods that may be harmful to the environment.

Students will work in teams to complete the electronics sections whilst other students create the wrap, students will have to take responsibility for their working environment and what stage of the design process they are at from one lesson to the next. Students will learn to give criticism to others in a way that helps students to make improvements to their products and be able to suggest their own improvements and what needs improving on their own projects.

Create a supportive community:

Students will work in teams to complete the electronics sections whilst other students create the wrap, they will need to support each other and play to their strengths and help others with their weaknesses. Give constructive criticism to help evaluate each other projects based on their clients needs, providing feedback for the students.
