Setting up the fixture level
Fixture: The number of the fixture is displayed. The number of
fixtures within this level is shown after the slash.
Method: You can choose between the WORKPIECE ORIENTED and
TOOL ORIENTED machining methods. The selected method is
assumed for the workpiece level and overwrites any existing
entries. In tabular view, WORKPIECE ORIENTED appears as WPO,
and TOOL ORIENTED appears as TO.
Use the CONNECT/SEPARATE soft key to mark fixtures that are to be
included for calculating the machining process for tool-oriented
machining. Connected fixtures are marked with a dashed line,
whereas separated fixtures are connected with a solid line.
Connected workpieces are marked in tabular view with the entry
CTO in the METHOD column.
The TO-/WP-ORIENTED entry cannot be made via soft
key. It only appears when different machining methods
were chosen for the workpieces in the workpiece level.
If the machining method was determined in the fixture
level, the entries are transferred to the workpiece level,
where they overwrite any existing entries.
Status: The soft key BLANK identifies the fixture and the
corresponding workpieces 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 fixture during machining. EMPTY appears in the
Status field.
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.
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.
