Path segmentation for single axes

If single axes are defined as punching/nibbling axes in addition to path axes, then the
automatic path segmentation function can be activated for them.
Response of single axis to SPP
The programmed path segment length (SPP) basically refers to the path axes. For this
reason, the SPP value is ignored in blocks which contain a single axis motion and an SPP
value, but not a programmed path axis.
If both a single axis and a path axis are programmed in the block, then the single axis
responds according to the setting of the appropriate machine data.
1. Standard setting
The path traversed by the single axis is distributed evenly among the intermediate blocks
generated by SPP.
Example:
N10 G1 SON X10 A0
N20 SPP=3 X25 A100
As a result of the programmed distance between strokes of 3 mm, five blocks are generated
for the total traversing distance of the X axis (path axis) of 15 mm.
The A axis thus rotates through 20° in every block.
