ICS DISPLAY
The GRAPHICS FUNCTION is a visual dry run of your part program without the need to move the
axes and risk tool damage from programming errors. This function is far more powerful than using the
DRY RUN mode because all of your work offsets, tool offsets, and travel limits can be checked before
any attempt is made to move the machine. The risk of a crash during setup is greatly reduced.
To run a program in Graphics, you must be in either MEM or MDI mode.
After loading the program into memory, select MEM (or MDI) and press the SETNG/GRAPH key twice to
select the Graphics Simulation mode. This function operates as if running a program on the machine, except
no physical machine action occurs.
The graphics screen is composed of the following areas:
DISPLAY TITLE AREA
The title area is on the top left line of the screen and indicates the display (GRAPHICS), the mode you
are in (MEM or MDI), the program number, and the current program line being executed. It is the same
as the top line of all displays.
KEY HELP AREA
The right side of the top line is the function key help area. Function keys that are currently available
are displayed here with a brief description of their usage.
LOCATOR WINDOW
The lower right part of the screen has two functions: it can display the whole table area and indicate
where the tool is currently located during simulation, or it can be used to display four lines of the
program that is being executed. The F4 key can be used to toggle between these two modes.
TOOL PATH WINDOW
In the center of the display is a large window that represents a lookdown perspective of the X-Y axes.
It displays tool paths during a graphics simulation of a CNC program. Rapid moves are displayed as
coarse dotted lines, while feed motion is displayed as fine continuous lines. The rapid path can be
disabled by Setting 4. The places where a drill can or canned cycle can be executed are marked with
an X. The drill mark can be disabled by Setting 5.
The tool path window can be scaled. After running a program, you can scale any portion of the tool path by
pressing F2 and then using the PAGE DOWN key and the ARROW keys to select the portion of the tool
path that you want to see enlarged. During this process, a rectangle will appear within the TOOL PATH
window and the Locator window indicating what the TOOL PATH window will represent when the zoom
process is complete. The KEY HELP AREA will flash, indicating that the user is zooming in the view. The
locator window always portrays the entire table with an outline of where the TOOL PATH window is zoomed
to. The PAGE UP key zooms out the rectangle one step. After sizing or moving the rectangle, pressing
the WRITE key will complete the zoom process and re-scale the TOOL PATH window. Pressing F2
and then the HOME key will expand the TOOL PATH window to cover the entire table. After the
TOOL PATH window is re-scaled, the TOOL PATH window is cleared and you must rerun the program,
or a portion of it, to see the tool path. The tool path is not retained in the control.
The scale and position of the TOOL PATH window is saved in Settings 65 through 68. Any scaling per-
formed on the TOOL PATH window is retained. You can leave graphics to edit your program and when you
return, your previous scaling is still in effect.
