In programming for C or Xaxis machining, this function is used to
output those NC data for calling a macro that performs interpolation rigid
tapping. A set of NC data for calling a macro that performs interpolation
rigid tapping is referred to as an interpolation rigid tapping cycle.
Those macros that perform interpolation rigid tapping must have already
been registered in the NC.

(1)Programming
Programming for outputting an interpolation rigid tapping cycle is
performed in the same way as that for outputting a normal rigid
tapping cycle.
1) Machining type
On the machining definition screen, select CAXIS TAP. or
Y–AXIS TAP. as the machining type.
2) Tool data
Use the tapping tool for milling.
3) Cutting conditions
On the definition screen, shown below, enter each data item.
TOOL TYPE TP=2 The rigid tapping type is specified(*1).. . . . . . . . .
CLEARANCE C1 =JJJJ The initial value is set to the value of. . . . . . . .
system parameter No.363 for the C-
axis, or the value of system parame-
ter No. 435 for the Y–axis.
C2 =
JJJJ The initial value is set to the value of
system parameter No.364 for the C-
axis, or the value of system parame-
ter No. 436 for the Y–axis.
CUTTING SPEED N =
JJJJ V*1000/DT*PAI(*2). . . .
(V = cutting speed value set in the
material data, DT = tool diameter val-
ue set in the tool data)
*1 When machining type 1 is selected, a general tapping cycle is
output.
When machining type 2 is selected, a normal rigid tapping cycle or
an interpolation rigid tapping cycle is output, depending on the
system parameter setting (see (2) below).
*2 The value for millingrelated tapping set in the material data
should be used as the initial speed value.
