Hole
centering
The easiest way to
center drill a hole
prior to drilling is to
use either CY-
CLE81 or CY-
CLE82
CYCLE81: With-
out delay at cur-
rent hole depth
CYCLE82: With
delay at current
hole depth
Select “Deep hole
drilling” using the
vertical SKs , and
then select “Deep
hole drilling” ,and
parameterize the
cycle according to
requirements.
N325 MCALL CYCLE82( 50.000, -3.000,
2.000, -5.000, 0.000, 0.200)
N330 X20 Y20 ; Hole will be centered
N335 X40 Y40 ; Hole will be centered
N340 MCALL
N345 X60 Y60 ; Hole will not be
centered
With the “OK” SK, the values and
cycle call will be transferred to
the part program as shown be-
low.
This will drill a hole at the current
position.
With the Modal call SK, holes will
be centered at subsequent
programmed positions until
cancelled with the MCALL
command in the part program.
The information is transferred as
shown below.
Parameters Meanings
RTP=50 Coordinate value of
turning position is 50
（absolute）
RFP=-3 Coordinate value of hole
edge starting position
under workpiece zero
point surface is 3
（absolute）
SDID=2
（frequently
used values
2~5）
Safety distance, feed
path changes from quick
feed to machine feed 2
mm away from RFP face
DP=-5 Coordinate position of
final drilling depth is -5
（absolute）
DTB=0.2 Delay of 0.2 s at final
drilling depth
The relevant cycle
can now be found
using the vertical
softkey on the
right.
