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:
– All strokes – even the one in the first block after activation – are executed at the block
end.
• SON/SONS:
– The first stroke after activation of the nibbling function is executed at the start of the
block.
– Each of the following strokes is initiated at the block end.

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.
