(incremental programming)
Q_: the peck depth each time（positive and incremental, minus mark will be ignored）
F_: feed speed, even if the canned cycle is cancelled, this modal data is still effective in the
subsequent machining.
K_: number of repeats (repeated movement and drilling, effective under G91 incremental mode)
The machining process of hole is as shown in Fig. 4-25. Slightly different from G73, the tool will
retract to plane R after each intermittent feed in G83. The ―‖ here, set by the parameter ―G73_G83
retract amount‖, refers to the distance between the feed plane where the cutter changes from G00 to
Gxx and the previous peck depth. G83 is especially for machining deep holes.
Fig. 4-25 G83 Machining Process
Process Description:
1. The cutter moves to the specified hole position (X, Y) in G00;
2. Moves to the specified point R in G00;
3. Drills down Q distance with respect to current depth in G01;
4. Retracts to the R plane in G00;
5. Moves down until distance (decided by the parameter ―Retract Amount‖) away from current
drill depth in G00;
6. Drill downs Q distance with respect to current drill depth;
7. Retracts to the R plane in G00;
8. Repeats above drilling operations until reaching point Z at the bottom of the hole;
9. Retracts to the initial point (G98) or point R (G99) in G00.
