Application
In the Test run operating mode, you can graphically check the
position of the workpiece blank or datum 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.
Use the soft key SW LIMIT MONITORING (in the second 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.
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.
Soft keys
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.
