Positioning along the X axis and Y axis, fast moving to R point. Perform drilling from R to Z. When arrived
at the bottom of the hole, suspend execution and fast moving back.
When G82 code section of the middle finger in the same program timing and M code, the positioning action
of M code execution at the same time, and then go to the next drilling movement. When specified repetitions K,
only in the first hole M code, the hole does not perform M code later.
Before using G82 drilling cycle, must through the M code specified spindle rotation.
When in a fixed loop program period specified in the tool length offset (G43 G44 G49), while positioning to
the R and offset.
P is pause time, at the bottom of the bore milliseconds, specify values for 100 times.
G82 and G81 movements are similar, the only difference is G82 increased suspended in the bottom of a hole,
and thus suitable for blind holes, dimpling or boring ladder hole processing, in order to improve the surface
machining accuracy at the bottom of the bore, and G81 is only applicable to general hole processing.
CAUTION:
1.
The tool radius compensation: in the use of a fixed cycle instructions, tool radius compensation is
ignored.
2.
Cancel the fixed cycle: cannot be used in the same program segment G82 and 01 group G code,
otherwise G82 is cancelled.
3.
Loop parameters: after the complete drilling cycle instruction, follow-up procedures section separately
specify the new cycle parameters (Z, R, P), a new cycle parameters cannot be effective; When the follow-up
process at the same time the number of the specified data and a new cycle parameters (Z, R, P), a new cycle
parameters take effect immediately, and in the subsequent program segment modal effect.

Perform drilling cycle, drill hole 1, pause for 2
seconds at the bottom of the bore then return to the
initial plane
X-50.
Drill hole 2, pause for 2 seconds at the bottom of the
bore then return to the initial plane
Y-160.
Drill hole 3, pause for 2 seconds at the bottom of the
bore then return to the initial plane
X50.
Drill hole 4, pause for 2 seconds at the bottom of the
bore then return to the initial plane
