9. SPINDLE SPEED FUNCTION
446
The descriptions given in this section (such as spindle gear switching and
M–type/T–type) are based on the explanation given in Section 9.3. Refer
to Section 9.3 as necessary.
The differences in the specifications for rigid tapping for the M series and
T series are described below.
The tapping cycle G84 and the reverse tapping cycle G74 can be used to
specify M series rigid tapping.
A tapping axis can be arbitrarily selected from the basic axes X, Y, and
Z, as well as axes parallel to the basic axes, by setting the corresponding
parameters accordingly (bit 0 (FXY) of parameter No. 5101).
The spindle operations of G84 and G74 are reversed with respect to each
other.
The face tapping cycle G84 and the side tapping cycle G88 can be used
to specify T series rigid tapping.
Depending on the rigid tapping command, rigid tapping can be performed
along the Z–axis (when G84 is used) or the X–axis (when G88 is used).
A reverse tapping cycle, like that supported by M series, is not available.
