The A axis thus rotates through 20° in every block.
2. Single axis without path segmentation
3. With/without path segmentation
• 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
programmed in the same block.
Requirement: The single axis is defined as a punching/nibbling axis.

The single axis traverses the total distance in the first of the generated blocks.
The response of the single axis depends on the interpolation of the path axes:
