Using PATTERN DEF
As soon as you have entered a pattern definition, you can call it with
the CYCL CALL PAT function (see "Calling a cycle with CYCL CALL PAT"
on page 44). 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).
