Defining a pitch circle
 Bolt-hole circle center X (absolute): Coordinate of
the circle center in the X axis
 Bolt-hole circle center Y (absolute): Coordinate of
the circle center in the Y axis
 Bolt-hole circle diameter : Diameter of the bolt-hole
circle
 Starting angle : Polar angle of the first machining
position. Reference axis: Reference axis of the active
machining plane (e.g. X for tool axis Z). You can enter
a positive or negative value
 Stepping angle/end angle : Incremental polar angle
between two machining positions. You can enter a
positive or negative value. As an alternative you can
enter the end angle (switch via soft key)
 Number of repetitions : Total number of machining
positions on the circle
 Coordinate of workpiece surface (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.
