2.3 PATTERN DEF pattern definition

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

Defining a single row

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.
Starting point in X (absolute): Coordinate of the
starting point of the row in the X axis
Starting point in Y (absolute): Coordinate of the
starting point of the row in the Y axis
Spacing of machining positions (incremental):
Distance between the machining positions. You can
enter a positive or negative value
Number of repetitions: Total number of machining
operations
Rot. position of entire pattern (absolute):
Angle of rotation around the entered starting
point. Reference axis: Reference axis of the active
machining plane (e.g. X for tool axis Z). You can
enter a positive or negative value
Coordinate of workpiece surface (absolute): Enter
Z coordinate at which machining is to begin
