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