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 (
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
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.

The path traversed by the single axis is distributed evenly among the intermediate blocks
generated by .
SPP
The single axis traverses the total distance in the first of the generated blocks.
