2. FUNCTION TO SIMPLIFY
(For the Power Mate i–D/D2)
This cycle performs tapping.
In this tapping cycle, when the bottom of the hole has been reached, the
spindle is rotated in the reverse direction.
G84 X_ Z_ R_ P_ F_ ;
X_ : Hole position data
Z_ : The distance from point R to the bottom of the hole
R_ : The distance from the initial level to point R level
P_ : Dwell time
F_ : Cutting feedrate
Tapping is performed by rotating the spindle clockwise. When the bottom
of the hole has been reached, the spindle is rotated in the reverse direction
for retraction. This operation creates threads.
Feedrate overrides are ignored during tapping. A feed hold does not stop
the machine until the return operation is completed.
Before specifying G84, use a miscellaneous function (M code) to rotate
When the G84 command and an M code are specified in the same block,
the M code is executed at the time of the first positioning operation. The
system then proceeds to the next drilling operation.
When a tool length offset (G43, G44, or G49) is specified in the canned
cycle, the offset is applied at the time of positioning to point R.
