8.13 Automatic path segmentation
If both a single axis and a path axis are programmed in the block, then the single axis re-
sponds 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 gener-
ated for the total traversing distance of the X axis (path axis) of 15 mm.
The A axis thus rotates through 20° in every block.
Fig. 8-43
2. Single axis without path segmentation
The single axis traverses the total distance in the first of the generated blocks.
3. With/without path segmentation
The response of the single axis depends on the interpolation of the path axes:
– Circular interpolation: Path segmentation
– Linear interpolation: No path segmentation
Response to SPN
The programmed number of path segments is applicable even if a path axis is not program-
med in the same block.
Prerequisite: The single axis is defined as a punching/nibbling axis.
