1 Necessary parameters (such as P, Q, X, Z, U, W, and R) must be set
correctly for an individual block that specifies a multiple repetitive
canned cycle.
2 In G71, G72, and G73 blocks having a sequence number specified
using P, always specify G00 or G01 in group 01, or otherwise a P/S
alarm (No. 65) will be issued.
3 None of G70, G71, G72, and G73 can be specified in the MDI mode.
If any of them is specified, a P/S alarm (No. 67) will be issued.
G74, G75, and G76 can be specified, however.
4 M98/M99 cannot be specified in a G70, G71, G72, G73 block, or any
block having a sequence number between those specified using P or
Q in a G70, G71, G72, or G73 block.
5 The following commands cannot be specified in any block having a
sequence number between those specified using P or Q in a G70, G71,
G72, or G73 block.
S One–shot G code except dwell (G04)
S G code other than G00, G01, G02, or G03 in group 01
S G codes in group 06
S M98/M99
6 It is possible to stop operation during multiple repetitive canned cycle
(G70 to G76) execution to allow manual intervention. Before
restarting the multiple repetitive canned cycle, be sure to return the
tool to the point of manual intervention, because the distance through
which the tool is caused to move by manual intervention is not
included in the absolute value (the actual tool position deviates by that
distance).
7 When G70, G71, G72, or G73 is executed, P and Q cannot specify the
same sequence number in one program.
8 For a multiple repetitive canned cycle, no figure can be specified using
the direct drawing dimension programming format.
9 Also for G74, G75, and G76, it is impossible to use floating–point
input for P and Q. The unit of travel distance and cutting depth is the
least input increment.
10 If #1 = 2500 is executed in a custom macro, 2500.000 is assigned to
#1, and P#1 is equivalent to P2500.
11 It is impossible to apply tool–nose radius compensation in G71, G72,
G73, G74, G75, G76, and G78.
12 A multiple repetitive canned cycle program cannot be used for DNC
operation.
13 No interrupt–type custom macro can be used during multiple
repetitive canned cycle execution.
14 No multiple repetitive canned cycle can be executed in the advanced
preview control mode.
