5.1 Simulation Mode of Oper
ation
Displays for contours: If several contours are defined in the NC
program, the simulation displays the corresponding contour symbols.
Selection of a contour
U Select “Setup > Contour selection.” The simulation opens the
“Contour selection” dialog box.
U In the “Contour selection” field, set the desired contour
Zero point shifts
In the “Contour selection” dialog box (Set up > Contour selection) you
define whether zero point shifts will be accounted for in the
simulation. As an alternative you can use the touchpad to click the
zero-point-shifts symbol in order to change the setting.
If you use the program section code CONTOUR and G99, no matter
what the status of the zero point shift:
„ The workpiece (the contour) is depicted at the position defined in
CONTOUR
„ G99 X.. Z.. shifts the workpiece to a new position
Contour symbols
Information of the contour symbols:
„ Qn (n: 1..4): Contour n
„ Position of the coordinate system
„ The symbol of the selected contour is marked
The simulation window displays the coordinate
system of the selected contour.
Including zero point shifts
„ The machine zero point is the reference point for the
positioning of contours and for the traverse paths.
„ Zero point shifts are included in calculation
Zero point shifts are not included in calculation:
„ The workpiece zero point is the reference point for the
paths of traverse
„ Zero point shifts are ignored
A change of status is not accounted for until the simulation
is restarted. The symbols are shown faded as long as the
changed setting is not yet in effect.
