PC-based machine-tool controller implemented as test bed for smart transducer interface

Machine-tool controllers are traditionally proprietary in design. Therefore, it is difficult to integrate third party hardware or software to enhance the functionality of either the machine tool or its controller. An open-architecture, PC-based controller merges as a good alternative. The Automated Production Technology Division at the National Institute of Standards and Technology, in collaboration with the US Navy, implemented an open-architecture, PC-based controller. This paper describes the design, implementation, and integration of this controller into a vertical machining center on the Portsmouth Naval Shipyard shop floor.
