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 in the
Test Run
mode: Press the BLANK IN WORK SPACE soft key to activate this
function. You can use the soft key SW LIMIT MONITORING (2nd
soft-key row) to activate or deactivate the function.
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. 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 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.
