Cash dispensing module

NCR (Manufacturing) Ltd., in Dundee, develops and produces automatic teller machines (ATM) for worldwide markets. It is the world leader in ATM quality and reliability. This article deals with, in the main, the cash dispensing module located within an ATM. This is a classic mechatronics example with the mechanical conveyor system for note movement controlled by a microprocessor, PROM, RAM, digital and analogue circuits. These in turn are controlled by the main ATM processor, running under an RMX operating system. The money movement and control mechansims will be addressed, as will the software procedures to ensure accurate note dispensing. To appreciate the manufacturing process discussion of the testing philosophy, the automated assembly line and robotic cell used to assemble the money cassettes is also included.
