15.4 Automatic path segmentation
15.4.1 General information
Function
One of the following two methods can be applied to automatically segment a programmed
traversing path:
●
Path segmentation with maximum path segment programmed via language command
SPP
● Path segmentation with a number of segments programmed via language command
SPN
Both functions generate sub-blocks independently.
In earlier systems
●
SPP<number>
corresponds to
E<number>
●
SPN<number>
corresponds to
H<number>
Since addresses
E
and
H
now represent auxiliary functions, language commands
SPP
and
SPN
are used to avoid conflicts. The new procedure is therefore not compatible with those
implemented in earlier systems. Both language commands (
SPP
and
SPN
) can be configured.
Note
The values programmed with
SPP
are either mm or inch settings depending on the initial
setting (analogous to axes).
The automatic path segmentation function ensures that the path is divided into equidistant
sections with linear and circular interpolation.
When the program is interrupted and automatic path segmentation is active (
SPP
/
SPN
), the
contour can be reentered only at the beginning of the segmented block. The first punch
stroke is executed at the end of this sub-block.
SPP
and
SPN
can be activated only if geometry axes are configured.
SPP
The automatic path segmentation function
SPP
divides the programmed traversing path into
sections of equal size according to the segment specification.
The following conditions apply:
●
Path segmentation is active only when
SON
or
PON
is active.
(Exception: MD26014 PUNCH_PATH_SPLITTING = 1)
●
SPP
is modally active, i.e. the programmed segment remains valid until it is programmed
again, but it can be suppressed on a block-by-block (non-modal) basis by means of
SPN
.
