The background drawing function enables the drawing of a figure for one
program while machining a workpiece under the control of another
program.
Procedure for Background Drawing
1 Press the
GRAPH
function key (
CUSTOM
GRAPH
for a small MDI).
2 Press the [PARAM] soft key. The following screen appears:

3 Press the [(OPRT)] soft key.
4 To select the program to be used for drawing, enter the number of that
program, then press the [O SRH] soft key. (The O number at the top
right of the screen indicates the selected program.) Repeatedly pressing
only the [O SRH] soft key selects the registered programs in turn.
To input a graphic parameter, the [INPUT] soft key can be used
instead of the
INPUT
MDI key.
5 Press the left–most soft key
(return menu key), to return the soft
keys to the state existing upon the completion of step 2.
6 Perform dynamic graphic display, as described in Section III–12.2.
Immediately after entering background drawing mode, the program
which was selected previously remains selected. Any program can be
selected for background drawing, by using the background drawing
screen.
If no program is selected prior to entering background drawing mode, the
program number is set to 0. In such a case, drawing cannot be started until
the program to be used for drawing is specified.
Separate tool offsets are internally provided for machining and
background drawing. Upon starting drawing or when selecting a program
for drawing, the tool offset data for machining is copied to the tool offset
data for background drawing. Changing a tool offset by using a G10
command during machining does not affect that for background drawing.
Similarly, changing a tool offset by using a G10 command during drawing
does not affect that for machining.
