COMPUTER USE IN THE CAR INDUSTRY
All products begin with an idea. In the past , car designers worked fist on paper. At a latter stage models were made in wood or fiberglass. Now everything is done using CAD (Computer-aided design ) programs. These programs allow designers to work in two or three dimensions (2-D or 3-D) but most new designs are created to be viewed from any angle. It can also be viewed by engineers and executives anywhere in the world.

The models have accurate dimensions and the design files can be sent to rapid modeling devices to produce a prototype. Before a single component is produced, programs will have worked out the forces acting on it. Crash conditions can be simulated to test the safety features of the car. Assembly can be simulated to work out the best way of building the car. This saves time and money.

For components such as engine parts, when the design is complete, the file is imported into a CAM (Computer-aided manufacturing) program. Here, all machining operations are planned. The file is then sent to a post-processor which converts the data into a set of instructions in a form which can be read by Computer numerical controlled (CNC) machine tools. These instructions are fed to a CNC controller which controls the machine tools which shape the finished product.

In complete Computer-integrated manufacturing (CIM), computers control the assembly line and monitor the supply of materials, ordering new supplies when needed. They can calculate when tools need to be replaced. Computers also permit changes in a product to be made easily. Orders can be customized to meet the needs of a particular client. ‘Special editions’ of cars can be produced to attract new customers to a model, for example the BMM Mini.

On the assembly line, computer-controlled robots are used for tarks such as welding and painting. Robots with sensors check the finished vehicle for defects. For example, they can check the paint thickness and how well the doors fit
