Punching and nibbling
12.2 Automatic path segmentation

Example:
N10 G1 G91 SON X10 Y10
N20 SPP=3.5 X15 Y15
When the total traversing distance is 15 mm and the path segment length 3.5 mm, the
quotient is not an integer value (4.28). In this case, the SPP value is reduced down to the
next possible integer quotient. The result in this example would be a path segment length of
3 mm.
Number of SPN path segments
SPN defines the number of path segments to be generated from the total traversing distance.
The length of the segments is calculated automatically. Since SPN is non-modal, punching or
nibbling must be activated beforehand with PON or SON respectively.
SPP and SPN in the same block
If you program both the path segment length (SPP) and the number of path segments (SPN)
in the same block, then SPN applies to this block and SPP to all the following blocks. If SPP
was activated before SPN, then it takes effect again after the block with SPN.

Note
Provided that punching/nibbling functions are available in the control, then it is possible to
program the automatic path segmentation function with SPN or SPP even independent of
this technology.
