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 the
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 indicated by a dashed line,
whereas separated fixtures are indicated by a solid line. Connected
workpieces are marked in tabular view with the entry CTO in the
METHOD column.
The TOOL/WORKPIECE 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 EMPTY POSITION soft key
if you want to skip the fixture during machining. EMPTY appears in the
Status field.
