Setting up details in the fixture level
Fixture:
The number of the fixture is displayed. The number of
fixtures within this level is shown after the slash.
Datum:
Enter the fixture datum.
Datum table:
Enter the name and path of the datum table valid for
machining the workpiece. The data is transferred to the workpiece
level.
NC macro:
In tool-oriented machining, the macro TCTOOLMODE is
carried out instead of the normal tool-change macro.
Safe height
(optional): Safe position for the individual axes
referenced to the fixture.
Setting up the workpiece level
Workpiece:
The number of the workpiece is displayed. The number
of workpieces within this fixture level is shown after the slash.
Method:
You can choose between the WORKPIECE ORIENTED and
TOOL ORIENTED machining methods. In tabular view,
WORKPIECE ORIENTED appears as WPO, and TOOL ORIENTED
appears as TO.
Use the CONNECT/SEPARATE soft key to mark workpieces that are to
be included for calculating the machining process for tool-oriented
machining. Connected workpieces are indicated by a dashed line,
whereas separated workpieces are indicated by a solid line.
Connected workpieces are marked in tabular view with the entry
CTO
in the METHOD column.
Status:
The soft key BLANK identifies the workpiece as not yet
having been machined, and enters BLANK in the Status field. Use
the soft key EMPTY POSITION if you want to skip the workpiece during
machining. EMPTY appears in the Status field.
Safety positions can be entered for the axes. These
positions can be read with SYSREAD FN18 ID510 NR 6
from NC macros. SYSREAD FN18 ID510 NR 5 can be used
to determine if a value was programmed in the column.
The positions entered are only approached if these values
are read and correspondingly programmed in the NC
macros.
Enter the method and status in the pallet or fixture level.
Then the entry will be assumed for all corresponding
workpieces.
For several workpiece variants within one level, the
workpieces of one variant should be entered together.
This way, the workpieces of each variant can be marked
with the CONNECT/SEPARATE soft key, and can be
machined in groups.
