The drilling positions must be programmed after you have
programmed the drilling technologies (centering, tapping, etc.).
The following position patterns are available:


Freely programmable positions


Position on a line, on a matrix or box

Position on a full or pitch circle
You can program several position patterns in succession (up to 20
technologies and position patterns together). They are traversed in the
order in which you program them.
The programmed technologies and subsequently programmed
positions are automatically chained by the control.
1. The first tool in the program (e.g. centering tool) initially traverses
all programmed positions.
Machining of the positions always starts at the reference point.
In the case of a matrix, machining is performed first in the direction
of the 1st axis and then back and forth.
The box and hole circle are machined counterclockwise.
2. All programmed positions are then machined with the second
programmed tool.
3. This procedure is repeated until each programmed technology has
been executed at all programmed positions.
Within a position pattern or on approach from one position pattern to
the next, the tool is retracted to the safety clearance, and the new
position or position pattern is then approached at rapid traverse.
You can include or skip any positions (see chapter entitled "Including
and skipping positions").
