10.4 Automatic path segmentation

Operating characteristics with path axes

All axes defined and programmed via machine data:

MD26010 $MC_PUNCHNIB_AXIS_MASK

are traversed along path sections of identical size with SPP and SPN until the programmed

end point is reached. This also applies to rotatable tool axes if programmed. The response

can be adjusted for single axes.

Example of SPP

Program code

N1 G01 X0 Y0 SPOF

N2 X75 SPP=25 SON

If the programmed path segmentation is not an integral multiple of the total path, then the feed

path is reduced.

; Position without punch initiation

; Nibble with feed value 25 mm; initiate punch

; before the first movement and after each

; path section,

; Position with reduced SPP value, because

; traversing distance < SPP value, and initiate punch

; after the movement.

; Reposition with punch initiation

; after each path section.
