3.19.2.2 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.
Behavior of the single axis for SPP
The programmed path segment length (SPP) basically refers to the path axes. Therefore, in a
block in which in addition to the single-axis movement and the SPP value no path axis has been
programmed, then the SPP value is ignored.
If both individual and path axes are programmed in the block, then the behavior of the single
axis depends on the setting of the appropriate machine data.
1. Default 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 stroke distance of 3 mm, for the total traversing distance of the X axis (path
axis) of 15 mm, 5 blocks are generated.
The A axis thus rotates through 20 degrees in every block.
1. Single axis without path segmentation
The single axis traverses its complete distance in the first of the generated blocks.
2. Different path segmentation
The behavior of the single axis is dependent on the interpolation of the path axes:
