G69. Drilling canned cycle with variable peck
The first drilling penetration is done in G07 or G50 depending on the value assigned to the parameter
of the longitudinal axis "INPOSW2 (P51)" and to parameter "INPOSW1 (P19)". This is important
to join a drilling operation with another one in multiple drilling so the tool path is faster and smoother.
If INPOSW2 < INPOSW1 in G07 (square corner).
If INPOSW2 >= INPOSW1 in G50 (controlled round corner).
If a scaling factor is applied to this cycle, it should be borne in mind that this scaling factor will only
affect the reference plane coordinates and drilling depth.
Therefore, and due to the fact that parameter "D" is not affected by the scaling factor, the surface
coordinate of the part will not be proportional to the programmed cycle.
Tool withdrawal
While machining, the CNC lets withdraw the tool to the starting plane stopping the spindle when
the tool reaches the starting plane.
Activating PLC mark RETRACYC (M5065) stops the main axis and the tool is withdrawn without
stopping the spindle. The spindle stops when the tool is retracted, once it reaches the starting plane.
Options after tool withdrawal
Once the tool has been retracted, the user will have the following options:
• Finish the hole.
• Go to the next hole.
• Go into tool inspection.
After this, the CNC will display the following message:
"To end the cycle, press START to skip to the next SKIPCYCL".
Finish the hole:
To finish the hole, press the [START] key.
It goes down in G0 with spindle running to 1 mm before the coordinate where the hole stopped. From
then on, it continues at the F and S programmed in the cycle.
Go to the next hole:
To go to the next hole, activate the PLC mark SKIPCYCL.
The CNC will display the following message:
"Press [START] to continue".
Pressing the [START] key, the CNC considers the cycle to be finished and continues with the next
block.
