3.19 Punching and nibbling
The axis accelerates at a rate corresponding to 50% of maximum acceleration.
Distance between holes from 2 mm to 10 mm:
Acceleration is increased to 100%, proportional to the spacing.
Distance between holes more than 10 mm:
Traverse at an acceleration of 100%.
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, to initiate a stroke at the same position, one of the punching/nibbling axes can be
programmed with a traversing path of 0.
