19.2 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 and the preset in the working
space of the machine. The graphics show the preset that has been
set in the NC program using Cylce 247 . If you have not set a preset
in the NC program, then the graphics show the active preset on the
machine.
You can active workspace monitoring in the Test Run operating
mode: to do so, press the BLANK IN WORK SPACE soft key. You can
activate or deactivate the function using the SW limit monitoring
soft key.
A transparent cuboid represents the workpiece blank. Its
dimensions are shown in the BLK FORM table. The control takes
over the dimensions from the workpiece blank definition of the
selected program.
For a test run it normally does not matter where the workpiece
blank is located within the working space. If you activate
workspace 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 preset for the Test Run operating
mode.
