6.5 Multi-channel step sequence programming (option)
If a job list or a corresponding list of the step editor (MCSP) exists in
the current workpiece directory, when simulation is selected, then the
machining list , is automatically pre-assigned - if this still does not
exist.
After confirmation of the machining list with OK, the relevant [JOB]
section is generated in the workpiece-specific DPWP.ini file.
The following entries are managed:
• Program name.type
• Channel number
• Spindle unit: Main spindle, counterspindle, variable
• Start label (path label)
• Stop label (path label)
• Length of the machining list (number of sections)
The machining list can be updated at any time via the
"Channel/spindle" menu.
The simulation sequence is controlled by the contents of the
machining list menu "Channel/spindle" and supports simulation of
multi-channel program coordination:
•
Selecting the list validates the specified operational sequence.
• In each sequence step the designated program can be fully
executed - as before - (i.e. from program start to M2/M30 or M17)
in the specified channel by leaving the fields "Start label" and
"Stop label" empty
• With each sequence step you can change to a different channel at
the section of another program (section by section channel
change) up to the specified "Stop label".
• If a label which was not previously defined as a "Stop label" for
the sequence is specified in the "Start label" field, an implicit
search run will be performed (without output of graphics) up to the
"Start label" in the selected program before the simulation run is
started.
•
If the label assignments are inconsistent, the simulation is reset to
the last valid state and a message is issued to this effect, e.g.
"Label xxxxxx not found. Adapt label definition in machining list or
adapt part program!".
• Each sequence step should be started separately and can also be
reset separately.
• Section-by-section change of the spindle unit within the step
sequence is permissible and controlled by means of keywords
from the program.
