Abstract :
At present, cost reduction and reliability improvement are the two essentials demanded of numerical controllers. This paper describes a controller which realizes these demands by introducing the time-division-multiplex technique for the digital part of the equipment, as well as newly developed stable and economical delay devices required for time-division multiplexing of digital equipment composed of condenser temporary storages and a multiphase synchronous pulse system.
