Using PATTERN DEF
As soon as you have entered a pattern definition, you can call it
with the CYCL CALL PAT function.
Further Information:
"Calling a cycle", page 48
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.

programming
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.
Defining individual machining positions
You can enter up to 9 machining positions. Confirm
each entry with the ENT key.
POS1 must be programmed with absolute coordinates.
POS2 to POS9 can be programmed as absolute and/or
incremental values.
If you have defined a Workpiece surface in Z not
equal to 0, then this value is effective in addition to
the workpiece surface Q203 that you defined in the
machining cycle.
POS1: X coord. of machining position (absolute):
Enter the X coordinate
POS1: Y coord. of machining position (absolute):
Enter the Y coordinate
POS1: Coordinate of workpiece surface (absolute):
Enter Z coordinate at which machining is to begin
POS2: X coord. of machining position (absolute or
incremental): Enter the X coordinate
POS2: X coord. of machining position (absolute or
incremental): Enter Y coordinate
POS2: X coord. of machining position (absolute or
incremental): Enter Z coordinate
