Abstract

The invention discloses a single channel and multi-channel switching control method in a numerical control system. The single channel and multi-channel switching control method includes the following steps that: a plurality of pairs of multi-channel identifiers and multi-channel terminators are arranged in the computer numerical control (CNC) part program, the CNC part program between each pair of multi-channel identifiers and multi-channel terminators is subjected to multi-channel control and decoding, and decoded data obtained after decoding are filled into data buffer zones of corresponding channels; buffer data of each channel are sequentially read out and preparing before interpolation is carried out; after the preparatory work of all the channels is completed, the data of each channel are sequentially taken out for interpolation, namely the motion amount of each axis is calculated, and the motion amount is output to an external machine control device; the CNC part program not located between the pairwise multi-channel identifiers and multi-channel terminators is subjected to single channel control; and finally whether decoding of the input CNC part program is completed is judged, the above steps are repeated if decoding is not completed, and control quitting is performed if decoding is completed. The single channel and multi-channel switching control method can achieve random single channel and multi-channel switching control and is wide in use and low in cost.
