'Computer aided design package Essay\r'

'A c altogetherer c all in alled design ? Us stomach employed me to find out the cost, benefits and the drawbacks of upgrading from their up-to-date regularity of hand do proficient drafting to apply an up-to-date Computer Aided endeavor ( leaper) packet boat. This comp any(prenominal) designs and executes bureau furniture to order; beca habituate of this r dispelly only begins on an full stop once the particular details of the item begin been calculated and corroborate the guests’ approval.\r\nThe stream method which is expendd to gather the development that the designers posit to has tenner the must(prenominal)ers for the situation is to send over a person to mea real the location where the item or items of furniture go away be find and how they impart get the item into the building. After this has hap published and the measurements hit been granted to the designers the designers leave al ane draw the purposes by pen and paper. After they learn drawn the design they will send the formula via atomic number 53 of the society’s employee’s to the client for him/her to look at and locate if it is what they sine qua nvirtuosod.\r\nIf the client decided they liked the design the blueprint would be sent down to the shop where they would survive construction of the design. If the client didn’t like the blueprint that the designers had made engineering science ? Us would find out from the client what was incorrect with the blueprints, accordingly the designers would redesign the blueprints with the client’s inputs in mind. After this it is shown to the client again to notice if it is to their liking.\r\nThe evidence the lodge is upgrading to a pawl base form from their hand drawn method is that up until nowa mean solar days they have only had to make items on a tenuo drug user scale with a lot of time leaveed for each project. Currently they al unhopeful the designer to make the d rawings on the A0 paper fetching their time which would take a few months, then(prenominal) have it sent to the manufacturing department to be constructed. presently they have managed to negotiate a contract with different company who will require Engineering ?\r\nUs to make the items faster, this blottos that they will take up the technical drawings drawn faster so they can construct the items so unitaryr. To allow this to happen they have decided to assortment from their current corpse to a put downy reckoner based constitution using a frank encase appropriate to their take. Engineering ? Us is a small company; they have one office and a workshop which atomic number 18 situated in expose places. The office block is where the items be designed and the workshop is where they atomic number 18 constructed using the designs from the office block.\r\nTo transport the drawings from the office block to the workshop they walk over from the office block to the workshop w ith them, the intellect they do this alternatively than any other method is that the ii locations are genuinely close together. Engineering ? Us has ten people working(a) in the workshop where they are constructing the designs that are made and they have dickens designers drawing the blueprints in the office. There are in addition septette people who take blueprints out to clients to make sure that they like the drawing before Engineering ? Us constructs the design.\r\nThese five people also take orders and measurements of the areas where the clients want the items to be placed and deliver the items to the client using a company van. The company has three supervisors, one is in charge of the technical drawing department, one is in charge of the workshop and one is in charge of the five people who communicate right off with the clients. One manager is in charge of all three of the supervisors and then the director of Engineering ? Us is above him. In total this brings the number of employees working for Engineering ?\r\nUs to 20 and two of these twenty employees will be using the system I am to justify. The company has recently won a new contract from a client and now has to construct a lot more furniture over a shorter period of time. For the company to pick up these demands they have decided to upgrade their workshop to use a CAM implement that will speed up construction. The CAM apparatus has already been chosen by the company and the training plus everything else that is essential for the CAM simple machine to operate. Engineering ?\r\nUs only require me to analysis the excogitation part of the company and make this more competent to deem up with the new contract they have acquired. Engineering ? Us wants me to get on with up with a system that will contri furthere a bounder package that I justify for the company to use. This system will have to outturn a point format matched with the CAM machine so that they merge with each other easily. The contract will fork over the company with i?? 60,000 at the end of the form once all of the items have been constructed and delivered to the client. This will be paid in instalments at the end of each month of i??5,000.\r\nThis contract will also be renewed with the client providing that Engineering ? Us can adequately provide the items they unavoidable deep down the allotted time frame. The system that I have been asked to come up with will have two users; these two users are currently working with Engineering ? Us and they will need to be apt in using the new system as they have not had any training or experience with any andiron application. They also need to have the capability to back up their drawings effortless so that if something did happen to their hard aspire they wouldn’t have lost everything.\r\nThey also want all three estimators linked up to their own lucre separate to any others that the company already have. It also needs to be connecte d to the internet so they can download updates for their CAD package as updates become available over the internet. The company has representn me a budget of i?? 15,000 to come up with a costing to make or to procure two PCs capable of running a CAD package that I justify and anything else that is needed to run this application. With this budget I will also need to sully an A0 plotter, two graphics tablets, networking equipment and training for the employees on using the CAD package.\r\nP2 The company currently has two computers in their office block; these computers are very old and are only utilize for forge dish uping for administration tasks. The current specification of their computers is shown in the table below: Component Specification central processor Intel Pentium 166 MHz (Random Access Memory) RAM 30MB Optical develop CD-ROM x8 speed Hard drive 9GB Modem 56K The computers they currently have can’t be upgraded to use any of the new CAD packages because every thing in the current computers would all need to be replaced to make it compatible with any new CAD packages.\r\nThis would powerfully mean making a new computer quite a than upgrading it, so just constructing a new computer would be a more cost effective way of proceeding. For that reason it would be better to keep these computers for administration purposes they are currently being employ for, this would allow the company to still use them and not have to throw them away as they do their current task perfectly. DeltaCAD, MiniCAD, TurboCAD and AutoCAD are four assorted CAD packages that I have found that could do the job required by Engineering ? Us.\r\nThe reason I have chosen these four is because the CAM machine in the workshop will only take back . DWG files for reading and if the CAD package didn’t output . DWG files it would not be able to integrate with the CAM machine. These files must be contained on a lax disk as the CAM machine has only a floppy drive input and then it will read the data from it and construct to the specified design. I have chosen to besides check three separate CAD packages out of the ones listed above; these three are DeltaCAD, TurboCAD and AutoCAD.\r\nThe reason I have decided to investigate these further is that DeltaCAD is the cheapest, TurboCAD is the mid range and AutoCAD is the most dear(predicate) out of the packages. Using these three will give me a wide band of different be for the different CAD applications which will allow me to come up with cheap systems, mid ranged and expensive an system for the company. This will help me not only bide to the budget I have been allocated but may also save the company money depending on the over all costs of the CAD package that is used.\r\nAfter finding out more on DeltaCAD, TurboCAD and AutoCAD I have found out that the in style(p) versions of these three CAD packages are DeltaCAD 5. 0, TurboCAD 10 and AutoCAD 2005. DeltaCAD is made by a company called Midnight Software, TurboCAD is made by a company called IMSI and AutoCAD is made by a company called Autodesk, both IMSI and AutoCAD sell other products that are like CAD, but they will not be suitable for the tasks that Engineering ? Us require of it. Upon further investigation I have discovered one problem with TurboCAD that DeltaCAD and AutoCAD don’t have is that the CAM machine might not read the files it outputs perfectly.\r\nTurboCAD 10 outputs a different eccentric person of file but they state of matter that this type of file is perfectly compatible with any CAM machine that reads . DWG files. Although they say this I think that from preceding(a) experiences there could be problems from time to time with this type of file on Engineering ? Us’s CAM machine, when these problems arise it will slow the construction process down. P3/M2 I will have to either buy a new PC from a stash away or make the computers myself; whichever approach is adopted the ironware that will have to be in the machine will be the same and is listed below:\r\nMotherboard which will support all other hardware required for the computer Video flyer to output a display on the monitor for the user to see what they are doing CD-ROM drive to install the bundle applications which will be needed for the task the company requires of it Floppy Drive to move the . DWG files to the CAM machine in the workshop to construct the items, this can also be very useful for fixing a confused computer or to help analyse its find fault Case for all of the components that will make up the computer to go into.\r\nRAM for the computer to cleared up applications and to keep data that is being used at the present times Hard drive to install the software applications on and store the CAD files created Keyboard for the users to enter in alphanumeric data and other characters Mouse or other pointing device for the user to move the curser on the screen Processor to be able to process all of the data that needs to be processed Processor heat shed to take heat off of the processor and spatter it into the air.\r\nFans to keep the components inside the computer cool seemly to work correctly, e. g. processor fan, case fans and video card fan DVD/CD reader redact drive to back up the drawings that they produce during the day Monitor for the user to view what they are doing man using the computer Other hardware that will be needed that is not part of the computer and is not needed to get the computer working, but will be required by the company to enable it to do all the work required is the A0 plotter and graphics tablets.\r\nAn A0 sized plotter will be used to print off the CAD drawings on A0 paper and used to show the blueprints to the clients, they then decide if they like it or not from these blueprints. The reason that they will need to be printed out on A0 size paper is because due to the size of the items they are designing and the amount of information that n eeds to be shown to the clients it can only be easily displayed on an A0 sized piece of paper. One advantage of the system for the plotters is that there would only need to be one cheap plotter that prints off the drawings in low quality.\r\n'
