Path Segmentation For Path Axes - Siemens SINUMERIK 840D sl Programming Manual

Work preparation
3.19 Punching and nibbling
Example 2
Automatic path segmentation should be made for the individual series of holes. The maximum
path segment length (SPP value) is specified for the segmentation.
Program code
N100 G90 X75 Y75 F60 PON
N110 G91 Y125 SPP=25
N120 G90 X150 SPOF
N130 X375 SPP=45 PON
N140 X275 Y160 SPOF
N150 X150 Y75 SPP=40 PON
N160 G00 Y300 SPOF

Path segmentation for path axes

Length of SPP path segment
SPP is used to specify the maximum distance between strokes and thus the maximum length
of the path segments in which the total traversing distance is to be divided. The command is
deactivated with SPOF or SPP=0.

Comment
; Position to starting point 1;
punch a single hole
; Maximum path segment length for
automatic path segmentation: 25 mm
; Punching off; positioning to
starting point 2
; Punching on; maximum path segment length
for automatic path segmentation: 45 mm
; Punching off; positioning to
starting point 3
; Punching on, instead of the programmed path segment
length of 40 mm, the calculated path segment length of
37.79 mm is used.
; Punching off; positioning
