Programming of the different models
Model RDT and RDT-IC
For efficient Tapping and production on CNC Machining Centre we
recommend the writing of a subroutine with high speed retract. As an
alternative a G85 boring cycle can be used. IMPORTANT NOTE at no
time should the G code for Exact Stop or Ramp be used with TAPMATIC
self-reversing Tapping Attachments. They will cause the tapping cycle
time to be significantly slower. We will gladly help with any programming
computation.
1.)
Rapid Traverse
to clearance
plane above
the hole
location.
2.)
Rapid Down to
1mm minimum
above
component.
3.)
Tap pitch into
component to
programmed
depth.
4.)
Retract Tapping
head at
1300mm/min,
specified
distance for
specific tapping
head to reverse
tap rotation.
5.)
Tap feed out of
to clearance
plane.
Example
(Fanuc programming)
Tapping attachment RDT25
Tap size M5 x 0.8
Speed
000 RPM
Feed at 100%
1600 mm/min
Subroutine:
Rapid traverse to 1 mm above component
Move in to 8 mm depth
(Please note: Actual depth slightly deeper than programme depth)
Retraction of 6 mm at 13‘000mm/min for changeover
(at fastest retraction speed up to 13‘000mm/min)
Move out at feed speed to 6mm above component surface
Main programme:
T01 M06 Tool change – tool #1
G00 G90 X25.0 Y25.0 chose work piece zero-point,
move toward X/Y-coordinates
S2000 M03
speed 2‘000 RPM, clockwise rotation of
spindle
G43 H1 Z25.0 M08 rapid feed to Z25, tool offset 1, coolant on
M98 P0004
retrieve subroutine O0004
G00 Y50.0
rapid feed to next position Y50
M98 P0004
retrieve subroutine O0004
Note: The only time during the cycle spent in the feed rate is the 1mm approach height
plus thread depth in and out. All other moves are at maximum speed.

Reversing tapping attachments require a

in order for the attachment to change
from forward to return movement.

Models SFT and SX
n Rapid traverse to clearance plane as recommended by respective
machine manufacturer.
n Cycle Rigid Tapping.
Models TA, TIC, TIM and SM
n Tapping cycle (G84).
n Rapid traverse to clearance plane as recommended by respective
machine manufacturers.
n Spindle feed (Z) apprx. 95% of theoretical pitch selected (TIM 100%).
Models SPD
n Utilize boring cycle (G85).
n Rapid traverse to clearance plane safety height, (depending on
thread size to be tapped 5–15mm above component).
n Choose spindle feed (Z) 98–100% of theoretical pitch selected to
thread depth required.
n Feed out (reverse Z) at 98–100% up to the clearance plane safety
height.
n Blind hole tapping or exactly defined depths. The Z feed plus the
self-feed within the Tapping unit calculate Z.*
*Note: this may have to be corrected to achieve the depth required due to any deviation
in the units built in self-feed and the response time of the machine.
Models NC (releasing drive)
n Utilize Tapping cycle (G84).
n Rapid traverse to clearance plan as recommended by respective
machine manufacturers.
n Spindle feed (Z) 95% of the theoretical pitch selected.
n Blind hole tapping or exactly defined depths. The Z feed plus the
self-feed within the Tapping unit calculates Z.
n Programme a short dwell into the Z movement to achieve full
self-feed (neutral).*
n Feed out to at least to the clearance plane.
*Note: this may have to be corrected to achieve the depth required due to any deviation
in the units built in self-feed and the response time of the machine.
Models ASR
n Sub routine: Feed 95% no dwell, feed out at 95% constant RPM.
n Rapid traverse to clearance plane safety gap (at least 10mm from
component).
n Feed out at least to clearance plane.
n For blind holes, machine feed to desired thread depth minus a short
allowance (apprx. 2mm) for the reaction time of the machine.
Models RSR
n Sub routine: Feed 64% no dwell, feed out at 68% constant RPM.
n Rapid traverse to clearance plane safety gap (at least 10mm from

n Feed out at least to clearance plane.
n For blind holes, machine feed to desired thread depth minus a short
