Hello there, my name is Mrs. Dami.

Thank you for joining me for your Design and Technology lesson today.

Now, you are probably going to be very excited at the prospect of manufacturing.

We've finally made it and you get to manufacture your absolutely wonderful and amazing design solutions.

However, the big question for today is, how do we manage to evidence our manufacture as we are manufacturing, and not forget to do it? Hard hats on, let's get exploring together.

Our outcome for today is we will be able to evidence key aspects of manufacture.

Our keywords for today are communicate, which means to express, share, or present ideas to others, evidence, which is documented proof, and then design decisions, as I'm sure you're all aware of now, is a deliberate choice to meet a design requirement or solve a problem.

We have two learning cycles for our lesson today.

First of all, manufacture, and second of all, evidencing manufacture.

So let's get cracking with manufacture.

The big picture for your iterative journey today is understanding the importance of evidencing manufacture, why we bother to do it.

Exploring key aspects to evidence during manufacture so you know what to evidence.

You are going to manufacture amazing design solutions for your iterative journey.

You've done so well on this journey, but it is important to evidence this stage, so to show that it is you that has manufactured your design solution and not your teacher, not your technician, not your friend, nobody else, that it's your work.

A successful start to manufacturing follows your wonderful manufacturing specification that you have written and also plans your wonderful plan for manufacture.

These are two really key parts that you need to look back on as your manufacturing to remind yourself of when to do what and the quality that it needs to be.

Throughout your manufacture, you may discover aspects that you need to research or iterate further.

Design decisions can still be made.

This is an iterative design journey, it is not a linear design journey.

Therefore, you can make design decisions at any point, just make sure that you record them.

Evidence of manufacture is important to demonstrate what, a, the technician made the product for you, b, it was you who manufactured the product, c, your understanding of safety and accuracy, d, any design decisions made throughout manufacture? Have a little think, come back to me when you've got an answer.

Well done if you managed to get b, c, and d.

It's so important to evidence your manufacture so you can demonstrate that it was you who made your product, that you understand safety and accuracy when manufacturing, and that you can record any design decisions that you made throughout manufacture.

Lucas chose to communicate his manufacture using pictures and descriptions.

You can see, you might not be able to read it, I don't want you to be able to read it, but you can see the way that he has laid it out with a step and a picture of what he did.

That can easily come from your plan of manufacture where you broke it into simple steps.

Try perhaps recording by taking a picture at each of those steps of your plan for manufacture.

Izzy chose to communicate her manufacturer using GIFS and explanations.

Now, you can't see her explanations here, but the GIFS clearly show what she's doing very clearly and how she's staying safe.

So for example, the way that she's holding the tenon saw correctly by pointing her finger and holding on to the piece of timber on the bench hook.

And then of course, with the knife, she's using a safety rule to make sure that her fingers are clearly in that dent to keep them away from the knife blade and to keep them safe.

She's clearly demonstrating safety through both of these.

The explanation will help though too.

Lucas, when he did his plan for manufacture, he separated it into separate parts for his product, and he decided to do exactly the same for recording and evidencing his manufacture.

He had a page for each of the separate parts and followed that plan for manufacture.

Now, it's so, so easy to become engrossed in manufacturing and forget to take pictures or GIFS.

I'm exactly the same, when I get making, I just get straight into it.

However, without the evidence, it's difficult to communicate the amount of effort and understanding that has gone into the process.

So be that a written reminder, be that a little post-it sticky note or something like that, just to remind you something that will work for you.

However you choose to communicate your pictures or your GIFS is individual choice, there's no set way.

However, it is important, whichever method you choose to communicate, to show evidence of the following.

We have safe working practises, quality control, accuracy and precision, specialist tools, equipment, and processes, your understanding of materials, and how you apply tolerances.

Now, you do all of these things naturally when you manufacture, but making sure that you remember to evidence them is the key part.

Andeep says, "I want to use pictures and GIFS and display them as a flow chart for each separate part of my design solution, but this was not mentioned on the previous slides, so I can't do it." Is this statement true or is it false? Have a little think, come back to me when you've got an answer.

Well done if you got false.

And why is that? However you choose to communicate your pictures or your GIFS is individual choice, be creative.

Onto task A.

Part one, prior to manufacture, it is important to consider two stages of your iterative journey.

I would like you to identify those stages.

Part two, I'd like you to consider suitable methods of communication for evidencing your own manufacture.

So think of your own iterative journey here and your own confidence, your own skills, and your own ways of creative communication.

Part one, prior to manufacture, it's important to consider two stages of your iterative journey, those being your manufacturing specification with exactly what your product must do, how it must do it, and all your measurements and details within it.

And then of course, you plan for manufacture, your step by step, what do you need to do, when.

Part two, I ask you to consider suitable methods of communication for evidencing your manufacturer.

Alex says, "I will use my mobile phone and take a mixture of photos and GIFS." Lori says, "We are not allowed mobile phones in my school, so I will use my teacher's tablet to take the photos.

I will be communicating my photos in a flow chart to show how it progresses." Two different ideas, both are great ideas.

Hopefully yours are also great too, well done with your hard work.

Onto learning cycle two, evidencing and manufacture.

We are going to explore key aspects to evidence during manufacture.

You are not limited to the ideas we share, you can bring your own to the table.

Some will be right for your iterative journey and others will not.

You may discover something you have not yet researched or developed.

Continue to make design decisions, but please continue to record them in your iterative journey too.

Now this is the big, big thing for today's lesson.

I want you to remember to evidence your manufacture.

So throughout the next few slides, you're gonna see this picture of a camera.

Hopefully that will help embed the idea that you need to take lots of pictures, lots of GIFS.

You need to remember to record your safe working practises.

Examples include such as the safe use of machines and tools, guards, PPE, and safely securing your work.

Now these are things that quite often you naturally do, but it's very easy to forget to evidence them.

So it's simple things such as timber being clamped to the bed of the pillar drill so that it doesn't spin, use of safe distances so there's not too many people around a particular machine, correct use of guard suitable for materials.

So when you are on that sanding machine, you move the guard down according to the size of the material that you are sanding.

And then of course PPE and hair tied up when using machinery.

They're all obvious things, but it's very, very, very easy to forget to evidence them.

So here's that picture of the camera, remember to evidence your manufacturer.

It's great to evidence the quality control that you do throughout your iterative manufacturing.

So examples include, trying to get the desired surface finish, testing functionality, checking that you meet health and safety requirements, and checking that you meet technical requirements.

So what does that look like in a workshop? That could be things like checking surface finishes, such as the removal of burrs or metal.

When you file it, you quite often get burrs that go over the edges.

Now you will always make sure that you remove those so that it's safe, but also that you've got a quality finish.

You do that anyway, make sure you take a picture of it.

You might check functionality.

A great way to check functionality and record that and evidence that is by perhaps taking a little GIF.

Perhaps you have worked really hard to make sure you get a consistent material thickness.

Here's a metal rolling mill, you might have set it at a particular measurement.

You could show yourself doing that with perhaps a steel rule to show that you've got that exact consistent material thickness between all of your pieces.

And then checking parts fit together, that's a bit of quality control.

So record it, evidence it, here's the camera again, evidence your manufacture in your iterative journey.

When we manufacture, we're quite often very accurate and precise.

Now we do that by weighing, measuring, getting consistent angles, marking out, using templates for multiple production.

But again, quite often we will forget to evidence that.

Let's take a look at what it looks like in the workshop.

So for example, weighing a silicon mix inside a mould, you will have to weigh to get exactly the right consistency between the two parts so that the silicon sets and works.

That is one way of showing accuracy and precision.

Quite often we set the drill depth so we only drill a particular way for a material.

Again, a great way of showing accuracy and precision, take a picture of it.

Sometimes we change the angle of the sanding bed so that we get a precise chamfer, chamfer being like an angle on the edge of our work.

Again, that shows our accuracy and precision.

We quite often accurately mark out, be that using tailor's chalk on fabric, be that using try-squares in a workshop, or engineer squares with metal.

Show that, evidence that for your work.

And then of course templates, we quite often make a template.

We might laser cut one, we might draw one on paper and cut it out so that we can get the same shape multiple times.

That again is evidence of accuracy and precision.

Here's the camera again, remember to evidence your manufacturer.

Andeep wants to show the functionality of a working circuit.

What would be the most suitable method of communication? A, photo shown before and after response, b, a GIF showing the response, or c, a written explanation? Remember, I'm asking for the most suitable.

Have a little think, come back to me when you've got an answer.

Fantastic, well done if you got b.

B, with a GIF showing the response will be fantastic for showing the functionality of a working circuit 'cause you see it in action.

Now that doesn't mean you can't use photos shown before and after response, but I was asking for the most suitable.

So Andeep says the GIF would clearly show the circuit functioning correctly.

He goes on to say, "I could also provide an explanation to go with the GIF" too, and that might aid the explanation of the gif.

Well done, Andeep.

You are likely to use a real range of specialist tools, equipment, and techniques throughout your manufacturer that are likely to be very different to the people sat next to you.

So I'm just gonna cover a few examples here, the list is endless.

If you use an overlocker, you could record the use of that, CAD cams such as the CNC router, the laser cutter, 3D printers, showing screenshots of your CAD to CAM.

And then of course different techniques, and there's tonnes of different techniques obviously.

But here's two lovely examples, enamelling and brazing.

Whichever techniques you use, show them off, show the before, show the after, show the process and the technique and the tool or the equipment actually working.

And don't forget, remember there's the camera again, evidence your manufacturer.

It's lovely to be able to show your understanding of materials and some of that will come from a bit of experimentation.

So for example, you might not have used metal before and you might explore a range of metal finishes.

Get some images of that, talk about it, explain what you found out, explain your understanding of that particular material.

You may also do some exploration for shaping and joining.

Here's one of my students who had melted down a whole load of bottle tops to create their own HDPE sheet.

And then this student goes on to think, how can they actually shape that material? So they popped it into the oven, they made their own jig for putting it in between, you can see the wooden part in the middle picture, and then they left it to call in a vice.

And the final picture on the bottom right is that HDPE having taken the shape of that mould.

You will explore, I'm sure, all sorts of types of material.

You know what I'm gonna say? Here's that camera, evidence that manufacturer.

A tolerance is an allowable variation within a measurement.

So examples within your work could include accurate measurement tools, measurements kept in a tolerance range, checking parts fit together correctly, and recording any of your adjustments.

So let's put this into a workshop application.

Lucas, when he was making the silicon part that went inside that funnel that goes on top of a jar to help open a jar, he wanted to make an accurate piece of silicon that fitted beautifully inside, that's the white funnel just there.

So what he did was he got his calculator, he got his compass, he got his protractor, and he went up to the maths department and asked them for some advice.

He then came down and created his own template, and then he cut that out of a piece of wood so that he could then create a mould to pour the silicon into.

Once he'd done that and once he'd accurately measured out the silicon to make sure that it's set correctly, he then had his silicon and he'd checked the tolerances for fit.

And because he'd done that so accurately, his tolerances were spot on, and it fit beautifully.

But it doesn't matter if it doesn't fit absolutely beautifully because you can record your design decisions for how you then change that so it does work.

What you might forget to do though is evidence this part with photos and GIFS, so please don't forget.

Time for our next check-in.

There will be lots of photos throughout manufacturing.

Which top tips for evidencing are correct? Is it a, photos of the final manufactured outcome will be enough to evidence your manufacturer, b, we record key aspects of evidence during every manufacturing session, c, keep up to date with evidencing your manufacturer in your NEA, and d, do not leave evidencing to the end of manufacture.

Have a think, come back to me when you've got an answer.

Well done if you've got b, c, and d, top tips for evidencing.

Please, please record key aspects of evidence during every manufacturing session, okay? Don't leave it to the end.

Keep up to date with evidencing your manufacturer in your NEA so that you don't miss out on any part.

And then of course, do not leave evidencing to the end of manufacture because you will have missed so many key aspects throughout manufacture and it'll be impossible to be able to show all of those clearly without that evidence.

Onto task B, part one, I would like you to evidence your amazing manufacturer, but remember, I would like you to demonstrate safe working practises, quality control, accuracy and precision, specialist tools, equipment, processes, your understanding of materials, and your application of tolerances.

You can do this, folks, good luck with your manufacturer, just do not forget to evidence.

Have good fun.

Hopefully you have evidenced your manufacturer as you went through, and hopefully you demonstrated the following: safe working practises, quality control, accuracy and precision, specialist tools, equipment, processes, your understanding of materials, and your application of tolerances.

Well done with manufacturing these amazing design outcomes and well done with all of your evidencing.

This brings us to the end of our lesson today, let's summarise what we have found out.

Throughout your manufacture, you may discover aspects that you need to research or iterate further.

Design decisions can still be made because it is an iterative journey.

Key aspects to evidence during manufacture include safe working practises, quality control, accuracy and precision, specialist tools, equipment, processes, understanding of materials, and how you apply tolerances.

Keeping on top of evidencing manufacture helps maintain a smooth iterative journey.

Please don't forget those photos.

Well done with all of your hard work today, and hopefully I'll see you in another lesson soon.

Take good care.
