G83 instruction is also used in the deep hole processing, the implementation of intermittent cutting feed to
the bottom of the hole, in the process of drilling out scraps from the hole. Hole processing action as shown in Fig.
13-5, along the X axis and Y axis positioning, fast moving to the R, from R point to Z point execution chip
drilling, when arrived at the bottom of the hole, fast moving back, return of d (intermittent feeding time was
decreased by fast before entering into work into that point to a cutting feed down the distance between the point)
can be set by parameter 0610.
Every time with a slightly different G73 is tool intermittent feed back to the R plane. Q means cutting depth
for each of the cutting feed, must be specified as positive, if Q is specified as a negative value, symbols will be
ignored. When G83 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.
When in a fixed loop program period specified in the tool length offset (G43 G44 G49), while positioning to
the R and offset. Before using G83 drilling cycle, must through the M code specified spindle rotation.
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 G83 and 01 group G code,
otherwise G83 is cancelled.
3.
Loop parameters: after the complete drilling cycle instruction, follow-up procedures section separately
specify the new cycle parameters (Z, R, Q), 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, Q), a new cycle
parameters take effect immediately, and in the subsequent program segment modal effect.
