Function
This MOD function enables you to graphically check the position of the
workpiece blank in the machine's working space and to activate work
space monitoring in the Test Run mode of operation.
The TNC displays a transparent cuboid for the working space. Its
dimensions are shown in the Traverse range table (standard color is
green). The TNC takes the dimensions for the working space from the
machine parameters for the active traverse range. Since the traverse
range is defined in the reference system of the machine, the datum of
the cuboid is also the machine datum. You can see the position of the
machine datum in the cuboid by pressing the soft key M91 in the 2nd
soft-key row.
Another transparent cuboid represents the workpiece blank. Its
dimensions are shown in the BLK FORM table (standard color is blue).
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 "Show tool datum" soft-key (2nd soft-key row).
For a test run it normally does not matter where the workpiece blank
is located within the working space. However, if you test programs
that contain movements with M91 or M92, you must graphically shift
the workpiece blank to prevent contour damage. Use the soft keys
shown in the following table.
You can also activate the working-space monitor for the Test Run
mode in order to test the program with the current datum and the
active traverse ranges (see table below, last line).
