Abstract: A new NC architecture,which is characterized by interpolating,encoding and dynamic simulating offline first,then implementing on-line decoding and control,ispresented in the paper.High precision-speed feature and high flexibility can be provided because the main function of processing is finished off-line.And high feed-speed canbe obtained by decoding on-line only.It has been implomented on a two dimensional manipulator.The experiment hasshown its advantages.
