FANUC Series 16/18/160/180-Model C for Lathe Operator Manual

OPERATION
12. GRAPHICS FUNCTION
B–62754EN/01
716
It is possible to draw the programmed tool path on the 9–inch or 14–inch
CRT screen, which makes it possible to check the progress of machining,
while observing the path on the CRT screen.
In addition, it is also possible to enlarge/reduce the screen.
The drawing coordinates (parameter) and graphic parameters must be set
before a tool path can be displayed.
With two–path control, the tool paths of two tool posts are displayed on
the same screen, one on the right and the other on the left.
Graphics display procedure
Set the drawing coordinates with parameter No.6510 before starting
drawing. See “Drawing Coordinate System” for the settings and
corresponding coordinates.
For the two–path control, parameter GRL (bit 0 of No. 6500) specifies
which tool post is displayed on which side (tool post 1 on the right or tool
post 2 on the right).

2 For the two–path control, determine for which tool post the data is
specified, using a tool post select signal.
Specify the PROGRAM STOP (N), AUTO ERASE (A), and
GRAPHIC CENTER (X,Y) parameters separately for each tool post.
The other parameters are common to both tool posts. It does not
matter for which tool post they are specified first.
3 Move the cursor with the cursor keys to a parameter to set.
4 Enter data, then press the

5 Repeat steps 3 and 4 until all required parameters are specified.
6 Press soft key

7 Automatic or manual operation is started and machine movement is
drawn on the screen.
