Control In The Motor Industry Essay, Research Paper Control in the Motor Industry To: Browns Motor Company From: x (IT Consultant for Control Systems Ltd) You can use control in industry to quicken the process of designing and manufacturing products. You can use a computer program to design products, and to send out instructions to make a machine operate in a particular way. Computer Aided Design Engineers and designers to help plan and construct things such as ships, bridges, roads, and in the case of the motor industry, cars, use Computer Aided Design (CAD). CAD software contains many features allowing you to: ¤ Calculate dimensions ¤ Draw objects in 2D, and display them as solid objects ¤ View objects from different angles ¤ Rotate drawings ¤ Simulate and test the finished design Using CAD software, designers can see any problems with the design before making is started. The following resources can be used to carry out CAD: ¤ Database ? Used to hold co-ordinates for detailed drawings ¤ Keyboard & Mouse ? Used to input co-ordinates for lines into the system, the mouse also allows you to move the cursor and click on things on the screen. ¤ Graphics tablet ? A flat pad, which is drawn on with a special pen. The surface is touch sensitive, movement is transferred to the monitor ¤ Scanner ? Can be used to input text and designs into the computer ¤ Digitiser ? Converts video signals into the computer from a video camera ¤ Joystick ? A joystick can be used to input dimensions into the computer To display your design you need to use the following devices: ¤ Screen ? A monitor with a high resolution should be used to give a clear image ¤ Printer ? Most suitable would be an ink jet or laser printer ¤ Plotter ? A computer controlled arm moves the pen up and down, and plotters can also be used to cut out shapes from material ¤ 3D-model maker ? A machine that takes a 3D object, then makes a model using laser beams on a material. The benefits of CAD are as follows: ¤ Drawings can be completed faster ¤ Changes can be made quickly, without you having to begin the design again ¤ You can zoom into the image to allow you to pay attention to fine detail However CAD does have it?s downfalls, which are the following: ¤ All the work could be lost if the system crashes ¤ Training staff to use the software is expensive ¤ Purchasing equipment and software needed is often costly ¤ Skilled computer operators are needed Computer Aided Manufacture CAM, or Computer Aided Manufacture is a process of helping stages of the process of production using computers. This is useful because: ¤ It speeds up the process of production ¤ Less workers need to be employed ¤ People do not need to be employed to complete tedious and boring tasks ¤ Less mistakes are made, and a high quality product is manufactured ¤ Less accidents are likely to happen, which makes the factory a safer place ¤ Machines can work 24 hours a day, increasing output, which will in turn increase sales and profit However there are some negative points to using Computer Aided Manufacture: ¤ Machines needed can be very expensive ¤ In the case of machines breaking down, repair can be costly You can use Computer Aided Design and Computer Aided Manufacture together to decrease manufacturing and increase time, costs, and sales greatly. You can use CAD to design the car and then pass the instructions to the CAM machines for the manufacture of the cars. Fewer errors will be made, money is saved, fewer people need to be employed, and the time take to design and make the vehicle is cut drastically. |
