23. MANUAL OPERATION
NC FUNCTION
321
In manual handle feed or jog feed, the following types of feed operations
are enabled in addition to the feed operation along a specified single axis
(X–axis, Y–axis, Z–axis, and so forth) based on simultaneous 1–axis
control:
D Feed along a tilted straight line in the XY plane (M series) (linear feed)
or in the ZX plane (T series) (linear feed) based on simultaneous
2–axis control
D Feed along a circle in the XY plane (M series) (circular feed) or in the
ZX plane (T series) (circular feed) based on simultaneous 2–axis

Once the CNC is put in the rigid tapping mode by issuing a program
instruction in the MDI mode, moving the taping axis with the manual
handle in the handle mode can cause rigid tapping to be performed.
Manual rigid tapping is available when parameter is set.
The program instruction is necessary to determine the lead of a screw to
be produced and enable the rigid tapping mode.
The program instruction must always specify a tapping axis. However,
a value specified in it must not cause the tapping axis to operate. Do not
specify an instruction for positioning to the position where a hole to be
made or to the R point; otherwise axis movement occurs.
(Example program)
M29 S1000;
G91 G84 Z0 F1000 ;
The spindle rotation direction for manual rigid tapping depends on the
specified tapping cycle G code and parameter.
