Basic Theory
G76 Boring cycle
Common programming structures:
G76 X—Y—Z—R—Q—P—F—K
Motion process:
① Drilling motion (-Z) → cutting feed
② Motion at the bottom of the hole →
spindle stop directional
③ Retraction motion (+Z) → fast feed
G76 application example program:
M3 S500 ;spindle rotation
G90 G99
G76 X300 Y-250 Z-150 R-100 Q5 P1000 F120
;after orientation bore 1st hole, then move 5 mm, stop for 1 s
at the bottom of the hole, back to the R point.
Y-50 ;bore 2nd hole (the same as 1st hole )
Y-80 ;bore 3rd hole (the same as 1st hole)
X10 ;bore 4th hole (the same as 1st hole)
Y10 ;bore 5th hole (the same as1st hole)
G98 Y-750 ;bore 6th hole, then move 5 mm,
stop for 1s at the bottom of the hole, back to the start point
position plane
G80 ;cancel fixed cycle
G28 G91 X0 Y0 Z0 ;back to reference point
M5 ;spindle rotation stop
G81 Drilling cycle (fixed point drilling)
Common programming structures:
G81 X—Y—Z—R—F—K
Motion process:
① Drilling motion (-Z) → cutting feed
② Motion at the bottom of the hole →
none
③ Retraction motion (+Z) → fast feed
G81 application example program:
M3 S2000 ;spindle rotation
G90 G99 G81 X300 Y-250 Z-150 R-10 F120
;after orientation drill 1st hole, back to R point
Y-550 ;after orientation drill 2nd hole, back to R point
Y-750 ;after orientation drill 3rd hole, back to R point
X1000 ;after orientation drill 4th hole, back to R point
Y-550 ;after orientation drill 5th hole, back to R point
G98 Y-750;after orientation drill 6th hole, back to start plane
G80 ;cancel fixed cycle
G28 G91 X0 Y0 Z0 ;back to reference point
M5 ;spindle rotation stop
M30
G82 Drilling cycle (countersink drilling)
Common programming structures:
G82 X—Y—Z—R—P—F—K
Motion process:
① Drilling motion(-Z) → cutting feed
② Motion at the bottom of the hole →
pause
③ Retraction motion (+Z) → fast feed
G82 application example program:
M3 S2000 ;spindle rotation
G90 G99 G82 X300 Y-250 Z-150 R-100 P1000 F120
;after orientation drill 1st hole, stop for 1 s at the bottom of the
hole, back to the R point.
Y-550 ;drill 2nd hole (the same as 1st hole)
Y-750 ;drill 3rd hole (the same as 1st hole)
X1000 ;drill 4th hole (the same as 1st hole)
Y-550 ;drill 5th hole (the same as 1st hole)
G98 Y-750 ;drill 6th hole, stop for 1 s at the bottom of the
hole, back to the start point position plane
G80 ;cancel fixed cycle
G28 G91 X0 Y0 Z0 ;back to reference point
M5 ;spindle rotation stop
M3
G83 Drilling cycle (deep hole drilling)
Common programming structures
G83 X—Y—Z—R—Q—F—K
Motion process:
① Drilling motion (-Z) → intermission
feed
② Motion at the bottom of the hole →
None
③ Retraction motion (+Z) → fast feed
