10.4 G83. Deep-hole drilling canned cycle with constant peck
Programming format in Cartesian coordinates:
G83 Z I J B K
Parameter definition:
Basic operation:
1. If the spindle was previously running, it maintains the turning
direction. If it is stopped, it starts clockwise (M03).
2. Rapid movement (G0) of the longitudinal axis from the starting
plane (Zi) to the reference plane (Z).
3. Drilling loop. The following steps are repeated "J" times.
• Drilling peck, at work feedrate. The distance indicated by "I".
• Rapid withdrawal (G0). The "B" distance or to the reference
plane.
• Rapid approach (G0) up to 1 mm from the previous drilling step
(peck).
Z Reference plane.
In G90, coordinate referred to part zero.
In G91, coordinate referred to starting plane (Zi).
If not programmed, it assumes as reference plane the current
position of the tool (Z=Zi).
I Drilling peck (step).
The sign indicates the machining direction. Positive towards
plus coordinate and negative towards minus. In the figure "I-".
J Number of pecks required by the drilling operation.
B Rapid withdraw (G0) distance after each drilling step.
If not programmed, it returns to the reference plane.
K Dwell, in seconds, at the bottom of the hole.
If not defined, it assumes a value of 0.
