- 888 -
CAUTION
The peck rigid tapping cycle command is valid within
a block containing G84.2 (G84.3), or it is made valid
by specifying the Q command in rigid tapping or
reverse rigid tapping cycle mode.
Rigid tapping command in feed-per-minute/feed-per-revolution mode
Rigid tapping may be specified in feed-per-minute mode (G94) or in
the feed-per-revolution mode (G95).
Example:
To tap a tread with a lead of 1 mm at a spindle speed 1000 rpm in
feed-per-minute mode, specify the following (in feed-per-minute mode,
the thread lead is F/S):
G94 ; Feed-per-minute command
G00 X120.0 Y100.0 ; Positioning
G84.2 Z-100.0 R-20.0 F1000 S1000 ; Rigid tapping
To tap the same thread as mentioned above under the same condition in
feed-per-revolution mode, specify the following (in the feed-per-
revolution mode, the thread lead is F):
G95 ; Feed-per-revolution command
G00 X120.0 Y100.0 ; Positioning
G84.2 Z-100.0 R-20.0 F1 S1000 ; Rigid tapping
NOTE
1 In feed-per-revolution mode, distribution is performed
by conversion to a command for feed per minute. So,
strictly speaking, this mode is not feed per revolution
mode. If spindle rotation is stopped for some reason,
movement along the tapping axis (Z-axis) does not
stop.
