Generate/do not generate graphics during
programming
While you are writing the part program, you can have the TNC
generate a 2-D pencil-trace graphic of the programmed contour.
Switch the screen layout to displaying program blocks to the left
and graphics to the right: Press the screen layout key and the
PROGRAM + GRAPHICS soft key
Set the AUTO DRAW soft key to ON. While you are
entering the program lines, the TNC generates
each programmed path contour in the graphics
window in the right screen half
If you do not wish to have the TNC generate graphics during
programming, set the AUTO DRAW soft key to OFF.
If AUTO DRAW is set to ON, with creation of 2-D line
graphics the control does not consider:
Program section repetitions
Jump commands
M functions, such as M2 or M30
Cycle calls
Only use automatic drawing during contour
programming.
The control resets the tool data if you reopen a program or press
the RESET + START soft key.
The control uses various colors in the programming graphics:
blue: uniquely specified contour element
violet: not yet uniquely specified contour element, can still be
modified by e.g. an RND
ocher: tool midpoint path
red: rapid traverse
