Behavior when quantity parameter is zero
The number of holes in a drilling pattern must be parameterized. If the value of the quantity parameter is zero when the cycle
is called (or if this parameter is omitted from the parameter list), alarm 61103 "Number of holes is zero" is issued and the
cycle is aborted.
Checks in case of limited ranges of input values
Generally, there are no plausibility checks for defining parameters in the drilling pattern cycles.
Row of holes - HOLES1
Programming
HOLES1 (SPCA, SPCO, STA1, FDIS, DBH, NUM)
SPCA REAL First axis of the plane (abscissa) of a reference point on the straight line
(absolute)
SPCO REAL Second axis of the plane (ordinate) of this reference point (absolute)
STA1 REAL Angle to the first axis of the plane (abscissa)
Range of values: –180<STA1≤180 degrees
FDIS REAL Distance from the first hole to the reference point (enter without sign)
DBH REAL Distance between the holes (enter without sign)
NUM INT Number of holes
This cycle can be used to produce a row of holes, i.e. a number of holes arranged 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.
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 at rapid traverse.
