A deadweight force standard machine is a mechanical structure that generates force by subjecting deadweights to the local gravitational field. Korea Research Institute of Standards and Science (KRISS) maintains several deadweight force machines for national force standards. Recently, KRISS has launched a project to develop a 1 MN deadweight force standard machine. The project is scheduled to be finished in 2014. This paper describes the design of the deadweight force machine. Concept and structure of the force machine are illustrated in the paper. The manufacturing and compensation/calibration of deadweights of the force machine are also described in this paper.
