The "Multiple clamping" function optimizes tool changes over several workpiece
clampings. On the one hand, this reduces downtimes and, on the other, elimi-
nates tool change times because a tool performs as many machining opera-
tions as possible in all clampings before the next tool change is initiated.
You can either process the same program multiple times on the clampings or
you can select different programs.
The function "Multiple clamping with different programs" is a software option with
the Order No. 6FC5 800--0AP14--0YB0.
If you are using large--area fixture plates on your machine, you do not have to
set up anything else. In the case of rotating clamping devices, on the other
hand, you must adapt a cycle to match the features of the clamping device so
as to ensure that the next workpiece can be turned to the machining position
after machining of the previous one (or for multiple clamping devices even while
the current workpiece is being machined).
Please proceed as follows:
Change the cycle CLAMP.SPF which is stored in the directory
S
CYCLES\SC\PROG\TEMPLATES_DEU or \TEMPLATES_ENG.
S Copy the cycle into the directory user or manufacturer cycles.
