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).
