Defining a single row
U Starting point in X (absolute): Coordinate of the
starting point of the row in the X axis.
U Starting point in Y (absolute): Coordinate of the
starting point of the row in the Y axis.
U Spacing of machining positions (incremental) :
Distance between the machining positions. You can
enter a positive or negative value.
U Number of positions : Total number of machining
positions.
U Rot. position of entire pattern (absolute) : Angle
of rotation 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 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.
