Punching and nibbling
12.1 Activation, deactivation
Initiation of the first stroke
The instant at which the first stroke is initiated after activation of the function differs
depending on whether nibbling or punching is selected:
• PON/PONS:
• SON/SONS:
Punching and nibbling on the spot
A stroke is initiated only if the block contains traversing information for the punching or
nibbling axes (axes in active plane).
However, if you wish to initiate a stroke at the same position, you can program one of the
punching/nibbling axes with a traversing path of 0.
Note
Machining with rotatable tools
Use the tangential control function if you wish to position rotatable tools at a tangent to the
programmed path.

– All strokes – even the one in the first block after activation – are executed at the block
