Requirements:
· In order to manage path markers (program labels, e.g.
MARKER1), they must be programmed at the required position in
the program.
· With the setting "Manage path markers" (settings -> Display/Colors
manage path markers) you can decide whether
Display and
· the path markers are to be displayed in the graphic and/or
colors...
· the associated intermediate model is to be saved.
Intermediate stages of the simulation model can be stored next to the
path markers, allowing synchronized resumption of simulation without
resetting the graphic that already exists.
You can skip any sections that are already optimized.
Block search:
In the menu "Block search" you can select the path marker you wish
to jump to.
Additional Note
· You can also load the machining list in menu "Channel/spindle"
directly from the current workpiece via the softkey "Program
selection" or from a JOB list.
The above mentioned operator options allow a multi-channel, section
by section program simulation with the following characteristics:
There are specific NC instructions for program coordination for
synchronizing program execution as required for multi-channel
manufacturing of workpieces: (INIT(..), START(..), WAITM(..) etc.). In
principle, they can be used to start independent program sections in
parallel channels almost simultaneously and synchronize them via
e.g. WAITM(Marker No., ...) once the associated machining
operations have been executed and before starting the next sections.
Simultaneous aspects can only be sequentially emulated with
simulation. NC program labels serve to mark program sections.
Emulating the multi-channel program coordination in the simulation
assumes that NC instructions for program coordination were marked
with NC labels (manually or automatically during program generation).
Simultaneous operational sequences which are independent of one
another are executed one after the other in the respective channels
(channel change per section required), before sequences are created
for the next sections in the same manner.
