Production PlanProduction Plan

Matthew Lane – Double Award GCSE Engineering

1. Metal Multi-toolThis component is made out of mild steel. This part took a long time to make due to the large amount of metal filing that had to be done. First the piece had to be cut from a long metal bar to the desired dimensions of 100x50mm. The 2D CAD metal multi-tool design was printed out using a printer. This paper was then used as a guide to show where either drilling, sawing or metal filling needed to be done to create the desired tool. I glued the paper guide to the metal and then centre punched multiple holes into the desired areas. They then had to drilled through with 5mm and 12mm drill bit. The multiple holes are drilled close together in order to keep the filing work to a minimum, and I also used a hacksaw to cut any parts of the metal off which were easier to cut instead if drilling. I then filed the metal down using metal files and metal needle files to make the edges smooth. It also takes off any excess metal to achieve the desired dimensions. To finish the metal off, wire wool was used to clean up and to remove any grease that the metal had left on it. I also used Brasso, which polishes the metal and then it finally needed to be cleaned with glass paper which gave it an attractive shiny finish. When all of these processes had been completed, different shapes had been cut out of the metal allowing them to work as a multi-tool.

2. Plastic Handles (2.1 – 2.4)This component is designed on a computer using a C.A.D (Computer aided design) program called ‘2D Design’. When the design was complete it was sent to the C.A.M (Computer aided modelling) machine. The C.A.M machine being used was a laser cutter. The laser cutter cut the desired shape from a piece of A3 size acrylic. Use of the laser cutter ensured that the cut would be accurate. This is because the laser cutter is a precision machine, and being computer controlled, there is no room for human error when this part is cut out.

When the shape had been cut out from the machine, it was necessary to push out the blank plastic holes where the laser had cut. The plastic spacers (Part 3) were then glued to the plastic handles. Plastic Handles Part 2.1 were glued using araldite to one of the plastic spacers (Part 3), which in turn was glued to Part 2.2. The same process was repeated for the plastic handle 2.3, 2.4 and the plastic spacer (Part 3) separating them.

• Plastic Spacers (2)This component was once again designed using a CAD program and was cut out using a CAM machine, which was the laser cutter. The CAD and CAM processes for the plastic spacers are identical to those of the plastic handles.

1. Metal Multi-toolWith this part I was required to cut a multiple shapes out of the metal to create different types of tools. By cutting out the shapes it allows this part to have multiple types of general purpose tools which would allow the metal piece to become a ‘metal multi-tool. There are many methods of machining which would allow us to create the multi-tool.

1. I could have drilled one or two holes at either end of the desired tool area to be removed, and then dismantle a junior hacksaw, so that the blade is inserted into one of the drilled holes. I could then re-assemble the junior hacksaw and could then saw down the marked dimensions. This would eventually give the desired dimensions but as with every method available, a lot of metal filling would need to be done. Even if I did the cut as accurately as I possibly could, the cut would not be as accurate as it could be.

2. Another method which I could have employed is Chain Drilling. This is when you centre punch multiple holes into the metal, and then drill through them. The multiple holes are drilled close together. I would then use a hacksaw to cut any excess metal off, and would then file the metal down to make the edges smooth and to take off any excess metal to achieve the specified dimensions. This method would also be time consuming. I could then cut the remaining shapes which are not suitable to be chained drilled, using a junior hacksaw. These areas include the screw driver and saw edge tools. The diagram below shows the ‘chain drilling’ method demonstrated on the shape I would need to cut. The red lines represent where I would drill the metal to create the desired multi-purpose tools.

Matthew Lane – Double Award GCSE Engineering

Either method would have been suitable to use, however I chose to use the ‘chain drilling’ method. I found this method reduced cutting time, but required more filling. Using needle files and metal files, I filed off all excess metal and to create certain tools (such as the saw edge), leaving a smooth and accurate finish. I found the ‘chain drilling’ method to be the most effective to cut out the shapes on the metal and by using the metal files, I found filing excess metal down using a file produced a much more accurate and cleaner finish to the part.

Alternative ProcessesAlternative ProcessesThere are multiple machining processes I could do for each component part that I have to make. There are 3 main components types in all.

DIY Multi-tool & Torch Gift ProjectDIY Multi-tool & Torch Gift Project Page Page 2323Matthew Lane – Double Award GCSE Engineering

2.1 – 2.4 Plastic Handles I could make the plastic base by marking the specified dimensions onto an A4 size piece of acrylic (plastic). I could

then cut along these marked lines using a Hegner Saw. The main reasons for not doing this are:

• It would be very time consuming having to manually cut the acrylic out by hand.• A more accurate cut will be created by using the laser cutter instead of cutting by hand, due to human error.• The acrylic would then need to be sanded down after the cutting to make the sides of the acrylic smooth and to

also correct the acrylic to the correct dimensions.

I used the laser cutter instead of manually cutting the acrylic out by hand. Advantages to using the laser cutter are that I could design the part quickly on a computer, and then cut it out using a C.A.M (Computer aided modelling) machine. In this case, I used the laser cutting machine.

Even though it would take time to design the part on a C.A.D (Computer Aided Design) program, it would be more time efficient to design the part accurately on a computer than cutting it out manually. The computer program I used is called ‘2D Design’.

Another reason why the Laser cutter is a more effective option is because the laser cutter is a precision machine. There is no room for human error when the part is cut out. This means that using the laser cutter is quicker and is more accurate means to creating this part.

3. (2) Plastic SpacersAll alternative processes are identical to those of component numbers 2.1 – 2.4, the Plastic Handles. This

component was once again manufactured using the laser cutter using the CAD program called 2D Design.

Alternative Materials & Material JustificationAlternative Materials & Material Justification

Matthew Lane – Double Award GCSE Engineering

1. Metal Multi-toolThis piece could have possibly been made out of wood, however as wood is relatively soft, it would be prone to deformation when either cutting, pulling, or

tightening other harder materials. This would lead to damage of the tool. Another disadvantage is that you would be restricted to the type of items that you could hold. A requirement of this part is that the multi-tool ‘must be robust enough to take general day to day use and abuse’. It must be able to cope with fairly large amounts of pressure to be used for general purpose activities. As metal is a hard material and wood is a relatively soft material the design of the multi-tool tends its self to be manufactured from metal. Therefore wood wouldn’t be the purposes we require it for.

We choose to use mild steel as it is harder than wood and can be used under great pressure and will not deform. Steel is very strong, but it takes a great deal of time to manufacture as all work is manual and is not processed by a computer. As a result, the extra time taken by the manufacturing of the metal slider is beneficial as it makes the multi-tool a much more robust product, allowing it to be used for general day to day use, which is stated in my original product specification.

2.1 – 2.4 Plastic Handles1. The first material is wood. Wood is fairly strong, light, and is easy to work with. However, wood is prone to splinters, so this material is not ideal for the

product.

2. Another material I could have used was Steel. Steel is very strong, but it would have made the tool very heavy, costly and would take a great deal of time to manufacture. By choosing steel I would have had less time to create other vital component pieces. Another disadvantage to steel is that if it is contact with water and air, it can be prone to rust.

The decision was made to use acrylic for the plastic handles, whilst using other materials for other specific component parts. I choose to use plastic because it is light, relatively strong and is easy to process. The advantage of using acrylic is that I could quickly design the component on a computer, and then send it to a laser cutter C.A.M machine. The advantage of using acrylic over using steel in the manufacture of the part is that it removes the need for intensive manual work in cutting and filing. As plastic doesn’t splinter it also has an immediate safety advantage over wood.

3. (2) Plastic Spacers(Identical to components 2.1 – 2.4 Plastic Handles). The main points for this component is that using acrylic is cheap and very easy to process as it does not

need any manual work due to the plastic being cut out on the laser cutter C.A.M machine.

There are multiple materials I could have used for each component part that I have to make. There are 3 main component parts in all.

The project we had to create was a multi-tool which had many tools on it, to be used for the DIY/Camping/General Purpose market. The device had to follow the product specification stated below:

The multi-tool will be aimed at the DIY, general purpose and camping market.It must be robust enough to take general day to day use and abuse.The product must be finished to a high quality and standard.It needs to sit ergonomically well in the users hand and to be anthropometrically suited to the human body.It must have a suitable protective case to house the multi-tool.The tools must sit safely within the case, when not in use.The multi-tool must be visually attractive and should include interesting shapes/angles.The tool must be able to be used for many functions and activities.The multi-tool will be required to have many useful & essential tools.It needs to be compact, so that it can be stored in a trouser pocket.It needs to be built and constructed for a low price, so that it can come free with a magazine.

For this project, I had to follow a design brief and technical drawings to manufacture the desired tool. I’m going to use “fit, form and function”“fit, form and function” considerations to evaluate this product.

Throughout the design processes, I wanted the multi-tool to be suited to a human hand, as an uncomfortable device is not very nice to use and would put customers off the product. For my plastic handles, I made cut outs in the plastic which allows the human hand to mould into these cut out so that a hand fits comfortably . This means that my product ’sits ergonomically well in the users hand and is anthropometrically suited to the human body’, which is stated in the original design specification.

FitDuring the manufacturing and construction of the tool, I managed to build the multi-tool to the specified dimensions. There was no need to change any of the original dimensions of the component parts. All parts fit and work in harmony to allow the tool to work.Therefore I was able to stick to the specified dimensions on my technical drawings sheet.

All component parts are within the specified sizes and I kept the quality of my dimensions high by measuring twice, and only cutting once. By using this method, the accuracy of our dimensions will be more accurate and fewer replacements parts would have been needed to manufacture. This maintains a high standard of quality and less time will be needed to replace or modify parts to fulfil their original needs. Using this method ensures that the tool ‘Has been manufactured to a high standard,’ as stated in the product specification.

FormWhen evaluating the form of the tool, we must investigate whether the materials used were suitable for their original purpose. Before we started the construction of the product we researched which materials would be suitable for each part. All the parts were analysed and assessed in the alternative materials & material justification sheet. Throughout the manufacturing and the construction of the tool, all parts served their purpose well and no obvious flaws have appeared using the chosen materials. As a result, all materials used, appear to be suitable for the product. Using the correct materials means that the tool is ’robust enough to take general day to day use and abuse’. No material alternatives were required to allow the tool to work more effectively and as such I believe the best materials have been chosen, therefore the tool fully fulfils this vital requirement.

All component parts have smooth edges; all burrs removed and have no sharp corners by design, so as to limit potential causes of injury. From the start of this project, a main priority was to make sure the tool is safely secured in some casing method. Therefore I chose for the plastic handles to rotate around, from when the tool is fully open to enclose and hide the metal multi-tool. By doing this the metal multi-tool sits safely inside the plastic handles, which then act as a case.. This means that the product’s ‘metal multi-tool tools sits safely within the case, when not in use’ and the product also has ‘a suitable protective case to house the multi-tool’.

A fundamental point since the begining of the project (and stated in the Design Brief) is that the multi-tool needs to be relatively cheap to mass produce, as it will need to sell with a DIY magazine. The most costly part of the multi-tool is the mild steel multi-tool component, as this had to be manually processed by using drills and metal files. However, mild steal is fairly cheap to buy. To make the product suitable for mass production, the metal would need to be processed by a metal CAM machine, and then it could easily be produced for mass production at a low price (manual labour of processing the metal is costly).

Also, if a CAM machine were to process the metal it could have a more accurate and higher quality finish. CAM Machines are procession tools, so there is no humans involved in the processing of the metal, thus there is no human error. Acrylic is cheap to purchase, and is easily processed by a CAM machine, like the Laser cutter we used so it could easily be made for mass production, at a low price. Overall, the multi-tool therefore fully qualifies that it can be ’built and constructed for a low price, so that it can come free with a magazine.’

FunctionThe main function of the tool is that it ‘will require to have many useful & essential tools.’ The tool achieves its purpose by having many general purpose tools capable of many functions for activities, and therefore it also meets the requirement specified in the product specification. This means that the multi-tool also fully qualifies that ‘the tool must be able to be used for many functions and activities’ stated in the design specification.

It was patently obvious from the begining that a multi-tool actually needed to be compact enough to be held in a human hand, therefore it would need to be small and compact to be seen as valuable tool. This then completes the specified ‘It needs to be compact, so that it can be stored in a trouser pocket.’

As well as the product being a suitable size, the tool also need to be ‘different’ and interesting. As my product includes an irregular but innovative method of enclosing and holding the tool, it could be seen as a valuable and original design of tool, which people would possibly like and desire. If the tool is attractive to a possible customer they are more likely to try and purchase (the magazine) it. As a result ‘The multi-tool is visually attractive and includes interesting shapes/angles’.

As stated in the design brief, the product that had to be created needed to be suited for the ‘Do it Yourself’ market (DIY). All of the tools which are currently on the tool, a DIY enthusiast would find essential for general DIY work. I have also kept in mind that this sort of tool would be very useful to a Camping enthusiast. It could also appeal to some one just wanting a general purpose multi-tool. In total , the multi-tool could appeal to a number of different markets therefore it is fully complete. To summarise, the multi-tool fits the design specification criteria that ‘The multi-tool will be aimed at the DIY, general purpose and camping market.’

I have also added other functions along the production of the tool. One of which is magnets located in the bottom of the plastic handles. These plastic handles allow the multi-tool to lock open so that it can click into place. This gives the multi-tool an expensive and executive feel. The magnets also require you to apply some force to separate the plastic handles, which makes the tool better to work with, as it stays open. This has been a valuable and worthwhile addition to the tool.

Matthew Lane – Double Award GCSE Engineering

I have thoroughly enjoyed making the multi-tool. I have completed all the necessary work which needed to be done to fully complete the tool. I feel that I have finished the whole product to a high standard, which is a fundamental point of the whole project (and specified in the Design Specification). I have further improved my knowledge on how to use certain machinery and designing products on paper and using CAD programs such as 2D Design and Google SketchUp. I have also completed every component part within the set time, keeping the quality of my products high and the dimensions of my parts accurate to their original dimensions. Overall I would say that this product is a massive success. I have thoroughly enjoyed designing, creating, using and evaluating this product. I am looking forward to the next project, and to further improve my knowledge and to create new and innovative products.

If I were to make this component again, I would have liked to have been more effective with my use of available time. Much time was consumed and wasted when filing the metal, and waiting to use certain metal files. I would have better used this down time to have been manufacturing other parts that did not require the use of metal files. If I were to do this, I would have been able to complete my component parts in a shorter amount of time, meaning that I could have completed the project in a shorter time. I therefore need to improve my overall manufacturing planning for future projects.
