Copy Turning Cycle (G86)
[Program format]
LE33013R0301000070001
[Function]
With the commands above, the control starts searching for the contour definition program beginning
with the sequence name NAT02. After assigning parameter data of D, F, U and W to NAT02, the
control starts the copy turning cycle.
[Details]
•
Do not designate an S, T, or M code in the G86 block.
•
The D word is used to specify depth of cut in each cycle and must be designated in the G86
block without fail.
The D word value must be positive. If not, an alarm results.
•
The F word specifies the feedrate for the blocks until an E word is designated in the contour
definition program.
If no F word is designated in the G86 block, the feedrate which was effective before the
execution of the G86 block is effective.
The F word must be positive. If not, an alarm occurs.
•
When no U and/or W word is designated, U and/or W is assumed to be "0".
•
U and W words must be positive or zero. If not, an alarm occurs.
