In this document I am going to be reporting on an engineering drawing. I am going to be giving reasons why it is suitable for its intended audience or in other words its intended user. I am also going to be saying how the drawing communicates information effectively and provide a good analysis of this engineering drawing.
In this engineering drawing you can clearly see that it is a first angle projection and that it is an orthographic drawing or a wall attachment adapter. I can tell this because it has the first angle projection symbol in the bottom right corner box which is below the title and also the way that the drawing is laid out. This type of drawing and this drawing itself will be used by the manufacturer to produce a product for a customer, this drawing will first be given to an engineer to interpret it and then the product will be produced by either using machinery or humans, this will be the final product. All of the information that giving’s you on the drawing is everything that you will need to know to be able to produce this product e.g. the dimensions and radius and the drawing lines are given. In this particular drawing the construction lines are used for the dimensions. This particular engineering drawing is very well laid out and the drawing is in the centre or the page and all of the important information such as the scale and size/date are all presented neatly in the bottom left corner so it is easy to read and also easy to spot where it is rather than all spread out over the page, also the text is a good size as it is readable and mostly consistent, this all makes it much easier to interpret the drawing. This is CAD designed product and not a pictorial hand drawn drawing, this makes it much easier to share as it is a computer file and can be sent via email, however it cannot be shared by posting it which also makes it safer and less likely to me damaged. This however make it harder to make changes to the drawing as you can’t just get a pencil and do it quickly you have to go through the hassle of having to log on, open the file and the change it and also it may be harder to get the author’s permission to change the drawing. In the manufacturing process there may be more than one drawing that is required to make the product, this is so that the manufacture can have a full understanding of the drawing and product that they are producing, this allows it to be accurately make to the correct specification. When the product is complex this is often what happens as there are too many parts and components to be able to fit on one sheet and make it much easier for the author and the manufacturer to use, this also make it much more accurate use as it shows that all the parts will be able to together to make the final product correctly. When the engineering drawing arrives at the manufacture there are many manufacturing methods used, the British method which is when an engineer uses several different machines and the own skills to produce the final product.
This drawing will be interpreted to make a prototype by the manufacture and is essential that the drawing is 100% accurate or there may be a problem in the production of the product. The drawing is basically meant to be a paper copy of the product therefore all the dimensions must be correct in order to be made the correct specification. If the drawing is not produced properly or is interpreted wrong there are many problems that it can use such as the product in this cause the wall attachment adapter not working when it is tested and therefore the drawing must be re-made to make sure that the prototype will work when they test it again. When this happens there are many problems and issues it causes to the manufacture and the company making the product the include; the waist or man power, waist of factory hours where other products could have been produces, waste or materials to make the prototype, Labor cost meaning that the company will have to pay the staff to do the job again to make sure it correct and also the image of the company, people will know that there has been a mistake when making a product as it must be published by the company by law and therefore this can damage the image or the company and people may lose faith in the company and think that they shouldn’t use the company in case this happens to their prototype of with the want to make and use. Along with this if there is an issue with making the prototype it means that the will be a delay in it getting to the customer which will cause the costumer extra problems because they may need it urgently.
