About Auxiliary NC Sequences
Auxiliary NC sequences produce a point-to-point tool path. They can be used to specify the connecting tool motions and change the tool axis orientation, if needed, between two machining NC sequences. They also allow you to access the on-machine probe functionality, and are available for any workcell.
 
* You do not have to specify a tool for an Auxiliary NC sequence. You can create Tool Motions even though no tool is specified.
