Function
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 datum set soft key.
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. You can view
the position of the active datum within the traverse range by pressing
the CURRENT DATUM soft key.
For a test run when working-space monitoring is deactivated, it 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).
