The easiest way to
drill a series of
holes is to use the
pre-defined “Hole
pattern” cycles.
The cycles can be
found and parame-
terized via the
“Drill.” SK.
The relevant cycle
can now be found
using the vertical
SKs on the right.
Select
“Hole pattern” using
the vertical
SKs ,and then se-
lect “Hole circle”,
and parameterize
the cycle according
to requirement.

N340 MCALL ; Modal Call OFF
With the “OK” SK, the val-
ues and cycle call will be
transferred to the part pro-
gram as shown below.
This will drill holes at the
positions defined from
within the cycle.
Parameters Meanings
CPA=36 Center of hole circle horizontal coordinate is 36 (absolute value)
CPO=24.1 Center of hole circle horizontal coordinate is 24.1 (absolute value)
RAD=10 Circle radius is 10 mm
STA1=90 Angle between the circle and horizontal coordinate is 90º
INDA=60 Angle between the circles is 60º
NUM=6 Drill 6 holes on circle
The cycle is used together with the drilling fixed cycle to decrease the hole clearance
