At the top of the machine is a stack of punched cards that would be fed into the loom to control the weaving pattern. This method of automatically issuing machine instructions was employed by computers well into the 20th century.
Computer-aided design (CAD) and computer-aided manufacturing (CAM) support customized production by providing the flexibility to manufacture specialized, small-batch items with the efficiency typically reserved for mass production.1
By integrating these technologies, manufacturers can adapt machinery to specific products through computer programming rather than manual retooling. The process supports customization in the following ways:1
- Design Flexibility: CAD allows designers to create, analyze, and modify complex product models digitally. This enables the testing of designs and production methods through simulationsāsuch as stress testingāwithout the time and expense of building physical prototypes.21
- Direct Integration: In a CAD/CAM system, design data is stored in a digitized format. This information is converted directly into instructions for production machines, such as numerically controlled tools and industrial robots, ensuring that the final product matches the precise specifications of the design.34
- Niche Production: Computers monitor assembly lines to ensure that different product variations or options are correctly fabricated, allowing for "niche" production where specialized items are created speedily in response to market demand.1
Ultimately, this integration reduces lead times and optimizes production flow, enabling firms to supply limited market segments with customized goods efficiently.31
