2,8.25.10 Improved Multiple Repetitive Cycle Function
(1) G74
executes a cycle as shown in Fig. 1,118,
2.8.25 .10.1 Nose R compensation can also be
executed in the finishing form program against the
G70 to G73 cycles.
This adds G41 and G42 to the G codes that can be
specified in the blocks of the finishing form
program (except for the Nsf. Nnf blocks).
Nose
R compensation is enabled by the G41 or G42
command blocks in the rough finishing cycle and
finishing cycle.
When commanding G41/G42 in the starting block of
the finishing form program,
also command the GOO
or GO1 move command.
Commanding in a single block is prohibited.

executed against the G70 to G73 cycles in the
finishing form program.
This
enables the F, S, T codes commanded in the
finishing form program (G70) and disables them
during outer form rough cutting,

2.8. 25.10.3 A finishing form program in which
start point and end point differ can also be
commanded against the G70 to G72 cycles.

(BA does not
need to be parallel with the Z-axis. )
. Upgrade of

finishing form) (2)”.
(BA does not need to be
parallel with the X-axis. )
2.8. 25.10.4 When both rough finishing margins I
and K are omitted against the G70 to G73 cycles,
finishing margin U and W can be executed as the
rough finishing margin.
Upgrading is enabled by related parameter #6009
D1 = 1.
2.8. 25.10.5 The A command (infeed steps) and
the B command (cutting tool width) are added to
the G74 (end face cutting cycle) and the G75
(outer diameter cutting cycle) functions to allow
execution of the groove machining canned cycle.
