13.2 Showing the workpiece blank in the
working space
Application
In the
Test Run operating mode, you can graphically check the
position of the workpiece blank or reference point in the machine’s
working space and activate work space monitoring: Press the
BLANK IN WORKSPACE soft key to activate this function. You can
activate or deactivate the function with the
SW limit monitoring
soft key (2nd soft-key row).
A 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 following table).

Note that even with

is shown in the working space as workpiece blank.
