G84. Tapping canned 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Activating PLC mark RETRACYC (M5065) stops the main axis and the spindle, the tool is withdrawn
changing the direction of the axis and spindle while keeping the machining F and S values. This
withdrawal will be to the starting plane.
The stopping and starting sequence of the spindle and the axis when tapping keeps the same
synchronism and dwells as during the execution of the canned cycle.
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Once the tool has been retracted, the user will have the following options: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.
The hole is repeated from the starting plane under the same F and S conditions without stopping
at the point where it stopped.
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.
