The TNC then performs the most recently defined machining cycle
on the machining pattern you defined.
A machining pattern remains active until you define
a new one, or select a point table with the SEL
PATTERN function.
You can use the mid-program startup function
to select any point at which you want to start or
continue machining.

The TNC retracts the tool to the clearance height
between the starting points. Depending on which
is greater, the TNC uses either the spindle axis
coordinate from the cycle call or the value from cycle
parameter Q204 as the clearance height.
