Information technologies in production

The use of new technologies is becoming more widespread in the textile industry. More companies are using Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM), Computer Numerical Control (CNC) and Computer-Integrated Manufacturing (CIM) in the processing, designing, planning and manufacturing stages of textile products. Many companies also use hi-tech machinery.

All products begin with an idea. In the past, product designers worked first on a paper. Now everything is done using CAD programs. CAD involves the use of computer hardware and design software to model textile ideas in 2D or 3D on the computer screen. CAD is a key part of the industrial design process because it enables manufacturers to test and modify ideas in 2D and simulate products on a screen in 3D. These virtual products can be shown to clients, who can then choose which one they would like to see as a made-up product sample. This reduces the need for producing a wide range of product samples, saving time and cost.

Once the design has been approved, the complete CAD file is imported into a CAM program, where the machining operations are planned. This data is then converted into a set of instructions which can be read by a CN controller. This automates all the machine tools which manufacture the product. This whole computerized process from design to manufacture is known as CAD/CAM.

The term CIM includes CAD/CAM but takes the process even further. In CIM, all aspects of manufacturing including the supply of products to quality assurance is computer controlled. This permits faster production times, a dramatic decrease in the number of workers required, and a lower risk of human error. CIM also allows manufacturers to move part of their operation to countries where costs are lower. It enables automated manufacture of textile products such as fibres, yarns, woven, knitted and printed fabrics.
