Simulation of the tilted plane
Contour graphics:
The simulation displays the YZ view of the
workpiece and the contours of the tilted planes in the side view. To
represent the drilling patterns and milling contours perpendicularly to
the tilted plane, i.e. without distortion, the simulation ignores the
rotation of the coordinate system and a shift within the rotated
coordinate system.
With contour graphics for tilted planes, please note the following:
 The parameter "K" of G16 or SURFACE_Y defines the "start" of the
drilling pattern or milling contour in the Z direction.
 The drilling patterns and milling contours are drawn perpendicularly
to the tilted plane. This results in a "shift" relative to the turning
contour.
Milling, drilling and boring operations:
When you use the side
view
to display the tool paths in the tilted plane, the same rules apply
as for the contour graphics.
When working in tilted planes, the front window shows the "outline"
of the tool. The tool width is simulated true to scale. In this way, you
can check the overlap of milling paths. The tool paths are also
represented true to scale (in perspective view) as line graphics.
In all "additional windows," the simulation shows the tool and the
cutting path when the tool is perpendicular to the relevant plane. A
tolerance of +/– 5° is taken into account. When the tool is not
perpendicular to the plane, it is represented as a "light dot" and the tool
path is depicted as a line.
Displaying the coordinate system
The simulation can show the shifted/rotated coordinate system in the
"lathe window," if required. To use this feature, you need to stop the
simulation.
 Press the Plus/Minus key, The simulation displays the
current coordinate system.
The coordinate system disappears when the next command is
simulated or when you press the Plus/Minus key once again.
