Plane definition
In the case of drilling cycles, it is generally assumed
that the current workpiece coordinate system in
which the machining operation is to be performed is
defined by selecting plane G17, G18 or G19 and
activating a programmable frame. The drilling axis is
always the applicate of this coordinate system.
A tool length compensation must be selected before
the cycle is called. Its effect is always perpendicular
to the selected plane and remains active even after
the end of the cycle (see also Programming Guide).
Spindle programming
The drilling cycles are written in such a way that the
spindle commands always refer to the master
spindle control. If you want to use a drilling cycle on
a machine with several spindles, you must first
define the spindle that is to be used for the operation
as the master spindle (see also Programming
Guide).
Dwell time programming
The parameters for the dwell times in the drilling
cycles are always assigned to the F word and must
therefore be assigned with values in seconds. Any
deviations from this procedure must be expressly
stated.
