10.7.22 Canned Cycle – High Speed Peck Drill G73
The G73 cycle is intended for deep drilling or milling with chip breaking. See also G83.
The retracts in this cycle break the chip but do not totally retract the drill from the hole. It is
suitable for tools with long flutes which will clear the broken chips from the hole. This
cycle takes a Q number which represents a "delta" increment along the Z-axis. Program
G73 X~ Y~ Z~ A~ B~ C~ R~ L~ Q~
¨ Preliminary motion, as described in G81 to 89 canned cycles.
¨ Move the Z-axis only at the current feed rate downward by delta or to the Z
position, whichever is less deep.
¨ Rapid back out by the distance defined in the G73 Pullback DRO on the Settings
screen.
¨ Rapid back down to the current hole bottom, backed off a bit.
¨ Repeat steps 1, 2, and 3 until the Z position is reached at step 1.
¨ Retract the Z-axis at traverse rate to clear Z.
It is an error if:
¨ the Q number is negative or zero.

10.7.24.4 G83 Cycle
The G83 cycle (often called peck drilling) is intended for deep drilling or milling with chip
breaking. See also G73. The retracts in this cycle clear the hole of chips and cut off any
long stringers (which are common when drilling in aluminum). This cycle takes a Q number
which represents a "delta" increment along the Z-axis. Program
G83 X~ Y~ Z~ A~ B~ C~ R~ L~ Q~
¨ Preliminary motion, as described above.
¨ Move the Z-axis only at the current feed rate downward by delta or to the Z
position, whichever is less deep.
¨ Rapid back out to the clear Z.
¨ Rapid back down to the current hole bottom, backed off a bit.
¨ Repeat steps 1, 2, and 3 until the Z position is reached at step 1.
¨ Retract the Z-axis at traverse rate to clear Z.
It is an error if:
¨ the Q number is negative or zero.

Le sens de la coupe, up ou down importe t il? Je n'ai pas bien compris cela...

Tu n'as pas Fusion360 en français ?
Il existe un excellent bouquin qui explore quasi toutes les possibiltés d'usinage avc F360. Je l'ai pris en epub.
