Automatic path segmentation

Path segmentation

When punching or nibbling is active, SPP and SPN

cause the total traversing distance programmed for

the path axes to be divided into a number of path

sections of equal length (equidistant path

segmentation). Each path segment corresponds

internally to a block.

Number of strokes

When punching is active, the first stroke is executed

at the end of the first path segment. In contrast, the

first nibbling stroke is executed at the start of the first

path segment.

The number of punching/nibbling strokes over the

total traversing path is thus as follows:

Number of strokes = number of path segments

Number of strokes = number of path segments + 1

Auxiliary functions

Auxiliary functions are executed in the first of the

generated blocks.

Size of path section (maximum distance between strokes); modal

Number of path sections per block; non-modal
