Operating and Programming — Milling
Basic Theory
The easiest way to drill a
series of holes is to use
the pre-defined “Hole
pattern” cycles.
The cycles can be found
and parameterized 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 select “Hole
circle”, and parameterize
the cycle according to
requirement.

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.
With the “OK” SK, the values and
cycle call will be transferred to the
part program as shown below.
This will drill holes at the positions
defined from within the cycle.
