1.12 Simulation

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.

The figure and the associated program section illustrate this situation.

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.
