Hello there.

My name is Mrs. Taylor and I'm so glad you could join me for our lesson today.

Our lesson today is "Batch production" and this is part of the "Collaborative design: tactile toys to teach" unit.

The outcome.

I can work with others to create a batch of the same design.

There are three keywords today.

Marking out, which is the process of measuring and drawing on a material before manufacture.

Tools, which are a device or instrument used to perform a task.

And cutting, the act of slicing, dividing, or removing something using a sharp tool.

The lesson has two parts, "Measuring and marking out" and "Cutting and shaping timbers." Let's begin with "Measuring and marking out." Marking out is measuring and drawing on a material before manufacture.

This is a critical task and should be carefully and accurately completed.

It helps to prevent material waste, ensure a good fit for assembly, save time, cost, and reduce errors.

Here we have a check for understanding.

When manufacturing, marking out accurately can, A, prevent material waste; B, makes the design better; or C, ensures a good fit for assembly.

Pause the video and have a go.

Fabulous, let's check.

That's right, it's both A and C.

Marking out accurately prevents material waste and ensures a good fit for assembly, well done.

A variety of tools are required when working with different types of materials, including when marking out materials.

Different materials require specific marking tools.

Using the wrong tool, such as a pencil on metal, can result in unclear or inaccurate marks.

Recalling measuring skills using millimetres will support successful marking out and the preparation of materials.

Equipment needed for marking out on timbers.

A pencil, a metal rule, and a try square.

Additional equipment that will support successful marking out on timbers.

A compass, masking tape, and a tape measure.

Here we have another check for understanding.

Name the pieces of equipment.

Pause the video and have a go.

Fabulous, let's check.

The first one is a try square and the second, a metal rule.

You may have described it as a steel rule.

Equipment to avoid.

Plastic rulers.

Measurements don't start at the ruler's edge, leading to inaccuracies when measuring.

And thick nibbed pens.

They produce a thick line that does not support accurate measuring and cutting.

When marking out materials, you should try to mark out designs from the edge or as close to the edges as possible.

For example.

This avoids waste and can make cutting less difficult.

Use a pencil, ruler, or tape measure to construct any dimensions, and always check your measuring.

Use a try square to start any straight lines to ensure lines are perpendicular to one another or the edges of the material.

Let's have a check for understanding.

What can you use to make marking outlines perpendicular to one another? Is it A, a board marker; B, a ruler; C, a try square; or D, a protractor? Pause the video and have a go.

Fantastic, let's check.

That's right, it's C, a try square, well done.

You could use a compass or a piece of string to mark out curves.

Here we can see the compass being used and a piece of string being used.

Making and using a card template is a successful way of marking out designs on timber.

This can be produced by hand using scissors, craft knives and a cutting mat, or produced using CAD and a laser cutter.

Use masking tape on the outside of your pencil lines to make the lines stand out clearly.

Add waste lines to remember what section of material you need and to avoid mistakes.

Here we have Task A.

In your collaborative design team, collect the materials needed for the batch production of your final design.

And part two, practise marking out all of the components needed to produce the team's final design.

The whole design team should do this together.

Use the success criteria on the next slide for guidance and support.

Consider the following.

Use a pencil, metal rule, or tape measure for accuracy.

Mark out from the edges and not in the middle.

Use a try square to ensure straight and perpendicular lines.

Use the correct equipment for curves and try not to create freehand.

Produce a card template to support marking out.

Add masking tape and waste lines for clarity when cutting.

Pause the video and have a go.

Wonderful, let's have a look at some of the answers you may have come up with.

As a design team, we collected our materials, which included plywood and MDF board and a Scots pine plank.

Aisha says, "We used our manufacturing specification to remember the materials and stock forms that we needed.

We also used this to remember details about dimensions too." And Lucas says, "We didn't forget about quality control.

We checked for straight edges using a try square and looked at the surface of the materials to ensure they had no defects." And part two.

We made card templates for most of the components and used them for marking out onto plywood and MDF board.

Jacob says, "Everyone in the design team checked the dimensions of the templates for quality control." And Sam says, "We used a pencil for marking out and we positioned the template as close to the edges as possible to not waste materials." Well done.

We now move to the second part of the lesson, "Cutting and shaping timbers." Design and technology involves the use of many different materials, each chosen for its unique properties and suitability for different purposes.

Selecting and using the appropriate tools and processes for a wide range of materials is an important task.

This is important because of efficiency.

The right tool ensures effective work, saving time and effort.

Quality, proper tools provide accuracy and a professional finish.

Safety, incorrect tools or handling can cause accidents or damage.

And material preservation.

Materials need specific tools to avoid damage.

Tool longevity, correct use prevents wear and extends tool life.

Here we have a check for understanding.

Read the sentence and complete by adding the missing word.

Pause the video.

Great, let's check.

Selecting and using the appropriate tools and processes for a wide range of materials is an important task, well done.

Cutting is shaping materials by removing excess parts.

When working with timbers, the essential tools you should use for cutting are a coping saw, a tenon saw, and a bench hook.

Here we have a check for understanding.

Name the cutting tools below.

Pause the video.

Wonderful, let's check.

We have a tenon saw and a bench hook, and these need to be used in conjunction with one another.

When cutting, we must consider the health and safety issues.

Saw blades are sharp and must be stored in locked cabinets and be carried carefully.

Saws create sawdust, which can be harmful if we breathe it in.

Therefore, it is important to remove the dust regularly using a vacuum with a suitable filter.

Timbers can be cut by hand either with a coping saw or a tendon saw.

Tendon saws are suitable for straight cuts in solid timber, and as we can see here, are used in conjunction with a bench hook.

Coping saws are suitable for curved shapes, and in this example, the timber is being held securely in the vice.

When cutting timbers with saws, it is important to hold the materials securely.

This makes cutting safer and easier.

Bench hooks are used for solid timber or dowel.

Vices are used for manufactured boards.

Here we have a check for understanding.

Which timber stock forms would a bench hook be suitable for holding? Is it A, a plank; B, MDF board; or C, a length of dowel? Pause the video and have a go.

Wonderful, let's check.

That's right, it's both A, a plank of solid timber, or C, a length of dowel, well done.

After cutting, finishing is required.

This helps remove more material, helps to achieve more accuracy with the shape, and produces smooth edges.

When working with timbers, tools you should use for finishing are files, a sanding machine, or abrasive papers.

A success criteria can be used to support the cutting and finishing for timbers.

Check the accuracy of marking out by using the phrase "measure twice and cut once." Select the appropriate tools.

Clamp solid timbers using a bench hook.

Clamp manufactured boards in a vice.

Use a tenon saw for straight lines in solid timbers.

Use a coping saw for curves.

Finish the edges using files, sanding machines, and abrasive papers.

And remove sawdust using a vacuum.

We now have Task B.

Part one, in your collaborative design team, cut, shape, and finish the components needed for the batch production of your final design.

Use the success criteria and refer to your manufacturing specification to remember the following.

The quantity needed, which is how many, the sales of production, who is completing what tasks, and quality control checks.

Pause the video and have a go.

Wonderful, let's check.

Your design team answers could include.

Aisha says, "Jacob and I are in cell one for batch production and are responsible for manufacturing five base components.

I was responsible for marking out and sawing.

I used a card template and a pencil to mark out the design on the MDF board.

I then used a vice and a coping saw to cut it out." Jacob says, "I was responsible for finishing the edges of the base components.

I used files of different sizes and shapes to help reduce bumps and smooth the edges.

I then used various grades of abrasive paper to ensure the edges were of the highest quality.

We repeated these tasks five times." Well done.

We now have a summary of our lesson today.

An essential part of production is the marking out phase.

This is a critical task and should be carefully and accurately completed.

Quality control, like checking measurements, should be implemented throughout production.

Cutting and shaping timbers requires a variety of tools and equipment, like coping saws and vices.

Having a clear understanding of how to use these tools in a safe and correct way is very important.

When producing a batch of products whilst working with others, it is important to refer to a manufacturing specification to be clear on the cells and manufacturing tasks that need to be completed.

I'm so pleased you could join me for the lesson today, well done.
