15.2 Showing the workpiece blank in the
working space
Application
This MOD function enables you to graphically check the position of
the workpiece blank or reference point in the machine’s working
space and to activate work space monitoring in the Test Run
mode of operation. This function is activated with the
BLANK IN
WORKSPACE soft key. You can activate or deactivate the function
with the SW limit monitoring soft key (2nd soft-key row).
Another transparent cuboid represents the workpiece blank. Its
dimensions are shown in the
BLK FORM table. The TNC takes the
dimensions from the workpiece blank definition of the selected
program. The workpiece cuboid defines the coordinate system for
input. Its datum lies within the traverse-range cuboid.
For a test run it normally does not matter where the workpiece
blank is located within the working space. However, if you activate
working-space monitoring, you must graphically shift the workpiece
blank so that it lies within the working space. Use the soft keys
shown in the table.
You can also activate the current datum for the Test Run operating
mode (see the last line of the following table).

Note that even with BLK FORM CYLINDER, a cuboid
is shown in the working space as workpiece blank.
When
BLK FORM ROTATION is used, no workpiece
blank is shown in the working space.
