Output of NC data for use in tapping processing
1) When MTF 1060 bit 7 is set to 1, an NC format with the G codes for
a canned cycle is output.

In this case the NC format output will conform to the settings of MTF
2059.
2059=5702, 5802, 6302, 1101, 0001, 0903, 0503, 0004, 0000, 0000
G17 G98 G84 X Z R F ;
G18 G99 G84.1
G19
With the above setting the tapping processing NC format output would
be G17 G99 G84 Z_ R_ F_ ;
2) When MTF 1060 bit 7 is set to 0, an NC format with the G codes for
a threading processing is output.

In this case the NC format output will conform to the settings of MTF
2022 for retapping and MTF 2059 for relief cutting.

With the above settings the tapping operation NC format output would be
either:
(1)Where spindle rotation direction ... SD = 0 (forward rotation)
G97 S_ M03;
.

G99 G32 Z_ F_ ; retapping . . . . .
M05; stop spindle . . . . . . . . . . . . . .
Z_ M04; return relief. . . . . . . . . . . .
In contrast,
(2)Where “spindle rotation direction ... SD = 1 (reverse rotation)
G97 S_ M04;
.
.
G99 G32 Z_ F_ ; retapping . . . . .
M05; stop spindle . . . . . . . . . . . . . .
Z_ M03; return relief. . . . . . . . . . . .
