Computer Aided Manufacturing(CAM) can be used to facilitate mass customization. Without CAM, and the CAD process that precedes it, customization would be a time-consuming, manual and costly process. However, CAD software allows for easy customization and rapid design changes: the automatic controls of the CAM system make it possible to adjust the machinery automatically for each different order.
The spectre of robots replacing workers, however, is currently a fallacy. Robotic arms and machines are commonly used in factories, but these do still require human workers. The repetitive tasks are delegated to machines; the human workers' job descriptions then move more towards set-up, quality control, using CAM systems to create the initial designs, and machine maintenance.
