Using PATTERN DEF

As soon as you have entered a pattern definition, you can call it
with the

CYCL CALL PAT function "Calling a cycle", page 50. 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 (see User's Manual, Test Run
and Program Run sections).
