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 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).

Defining individual machining positions

You can enter up to 9 machining positions. Confirm
each entry with the ENT key.

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.

X coord. of machining position (absolute): Enter X
coordinate

Y coord. of machining position (absolute): Enter Y
coordinate

Coordinate of workpiece surface (absolute): Enter
Z coordinate at which machining is to begin
