Function
With this cycle you can program a row of holes, i.e. a
number of holes that lie along a straight line or a grid
of holes. The type of hole is determined by the
drilling cycle that has already been called modally.
Sequence of operations
To avoid unnecessary travel, the cycle calculates
whether the row of holes is machined starting from
the first hole or the last hole from the actual position
of the plane axes and the geometry of the row of
holes. The drilling positions are then approached
one after the other in rapid traverse.
