15.6 Sub Part System Control II

15.6 Sub Part System Control II
This function activates and operates any non-operating part system (sub part system) in the multi-part system.
Using sub part systems enables parallel operation between an operating program in main part system and a program called
with Sub part system control II (G144).
Sub part systems does not have any controllable axes soon after the activation. When an axis is needed to be controlled in
sub part system, command the arbitrary axis exchange control (G140) to give sub part system authorization to control the
axis.
In the machine configuration below, when performing the back drill machining (machining (a)) and the cutting by tool
(machining (b)), machining (a) and (b) are operated in order only with main part system, however machining (a) and (b) can
be operated simultaneously by using the sub part system in addition to the main part system. Accordingly, the cycle time will
be shortened. In the usage example below, T2 (time when machining (b) is completed) is shorter.
