3.2.2 Channel

NOTE

runtime component of the CNC which executes an NC program
This execution may happen in Block Sequence mode (execution of the next NC command starts as soon as the previous has completed), or Single Block Mode (NC channels stops and waits for a NC Start signal to resume executing the next NC program block). A channel contains an assigned set of axes which can be moved in a synchronised interpolated manner. Auxiliary axes may also be assigned to a channel which will usually be commanded in a synchronized uninterpolated manner. An active NC channel runs current NC programs which relate to the workpiece etc. Depending on the machine there may be several active NC channels running simultaneously.
