After positioning along the X–axis, the spindle is stopped at the fixed
rotation position. The tool is moved in the direction opposite to the tool
tip, positioning (rapid traverse) is performed to the bottom of the hole
(point R).
The tool is then shifted in the direction of the tool tip and the spindle is
rotated clockwise. Boring is performed in the positive direction along the
Z–axis until point Z is reached.
At point Z, the spindle is stopped at the fixed rotation position again, the
tool is shifted in the direction opposite to the tool tip, then the tool is
returned to the initial level. The tool is then shifted in the direction of the
tool tip and the spindle is rotated clockwise to proceed to the next block
operation.
Before specifying G87, use a miscellaneous function (M code) to rotate
the spindle.
When the G87 command and an M code are specified in the same block,
the M code is executed at the time of the first positioning operation.
The system then proceeds to the next drilling operation.
When a tool length offset (G43, G44, or G49) is specified in the canned
cycle, the offset is applied at the time of positioning to point R.
Before the drilling axis can be changed, the canned cycle must be
canceled.
In a block that does not contain X, Z, R, or any additional axes, boring is
not performed.
Be sure to specify a positive value in Q. If Q is specified with a negative
value, the sign is ignored. Set the direction of shift in bits 4 (RD1) and
5 (RD2) of parameter No. 5101. Specify Q and R in a block that performs
boring. If they are specified in a block that does not perform boring, they
are not stored as modal data.
Do not specify a group 01 G code (G00 to G03) and G87 in the same block.
If they are specified together, G87 is canceled.
In the canned cycle mode, tool offsets are ignored.
