The rigid tapping command format for the T series is described below.
For an explanation of the command format used with the M series, refer
to Section II.13.2.2 of the “Operator’s Manual for Machining Center
(B–63534EN) ”.

Specifies the position of an R point
Specifies the position of the bottom
face of a tapped hole
Specifies a tapping position.

The rigid tapping mode can be specified by using any of three methods:
D Specification of M29S**** before specifying a tapping cycle
D Specification of M29S****in the same block
D Enabling rigid tapping to be performed without specifying M29S****
When using the third method, specify S**** either before or in a block
containing G84 (G88).
Thus, the spindle stops, after which the tapping cycle specified next is
placed in rigid tapping mode.
Rigid tapping mode will be canceled by G80;. Note, however, that a G
code for another canned cycle, or a group 01 G code will also cancel rigid
tapping mode.
When rigid tapping is terminated by a command issued to cancel rigid
tapping mode, the spindle stops. (Output to the spindle is equivalent to
the specification of S0.)
A reset (by means of the RESET button or an external reset) can also
cancel rigid tapping mode. Note, however, that canned cycle mode is not
canceled by a reset.
