Defining individual frames
U Starting point in X (absolute): Coordinate of the
starting point of the frame in the X axis.
U Starting point in Y (absolute): Coordinate of the
starting point of the frame in the Y axis.
U Spacing of machining positions X (incremental) :
Distance between the machining positions in the X
direction. You can enter a positive or negative value.
U Spacing of machining positions Y (incremental) :
Distance between the machining positions in the Y
direction. You can enter a positive or negative value.
U Number of columns : Total number of columns in the
pattern
U Number of lines : Total number of rows in the pattern
U Rot. position of entire pattern (absolute) : Angle
of rotation by which the entire pattern is rotated
around the entered starting point. Reference axis:
Major axis of the active machining plane (e.g. X for
tool axis Z). You can enter a positive or negative value.
U Rotary pos. ref. ax. : Angle of rotation around which
only the major axis of the machining plane is distorted
around the entered starting point. You can enter a
positive or negative value.
U Rotary pos. minor ax. : Angle of rotation around
which only the minor axis of the machining plane is
distorted around the entered starting point. You can
enter a positive or negative value.
U Workpiece surface coordinate (absolute ): Enter Z
coordinate at which machining is to begin.
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.
