2.3 PATTERN DEF pattern definition

Defining individual frames

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.
The Rotary pos. ref. ax. and Rotary pos. minor
ax. parameters are added to a previously performed
rotated position of the entire pattern.
Starting point in X (absolute): Coordinate of the
starting point of the frame in the X axis
Starting point in Y (absolute): Coordinate of the
starting point of the frame in the Y axis
Spacing of machining positions X (incremental):
Distance between the machining positions in the X
direction. You can enter a positive or negative value
Spacing of machining positions Y (incremental):
Distance between the machining positions in the Y
direction. You can enter a positive or negative value
Number of columns: Total number of columns in
the pattern
Number of lines: Total number of rows in the
pattern
Rot. position of entire pattern (absolute): Angle
of rotation by which the entire pattern is rotated
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
Rotary pos. ref. ax.: Angle of rotation around which
only the reference axis of the machining plane is
distorted with respect to the entered starting point.
You can enter a positive or negative value.
Rotary pos. minor ax.: Angle of rotation around
which only the minor axis of the machining plane is
distorted with respect to the entered starting point.
You can enter a positive or negative value.
Workpiece surface coordinate (absolute): Enter Z
coordinate at which machining is to begin
