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).
