Definitions

  • a numerical path control system including a time shared digital computer generating for each of a plurality of axes regularly recurring numerical excursion commands.
  • a two axis system is shown to be capable of deriving from a small number of data words successive straight line path or circular arc path command signals at a rate of 50 times a second and of converting these into intennediate or secondary command signals which are applied to the servos of the machine axes at a rate of 500 times a second.
