HEIDENHAIN CNC Pilot 4290 Description of the Y axis - Manual (Page 42)

Y Axis 42
3 Y Axis in Simulation
Select the combination of windows best suited to
the machining that you wish to inspect (dialog box:
”Window selection”):
■ Lathe window
■ Front window
■ Side view (YZ) alternatively Surface window
The front window, surface window, and side view
are considered supplementary windows. Traverse
paths are not shown in the supplementary windows
until the C axis has been oriented or a G17 or G19
has been executed.
G18 or a C axis out of orientation stops output of
the traverse paths in the supplementary windows.
As an alternative, you can set the ”path display in
supplementary windows” to always (in the
”Window selection” dialog box). Then, each traver-
se path will be shown in all simulation windows.

■ The front and the surface windows operate with a
”fixed” spindle position. If the lathe turns the workpiece,
the graphic simulation moves the tool while the
”workpiece” remains stationary.
■ Contours and milling contours in the YZ plane appear
smaller in the developed surface. The line segments are
drawn ”on the milling floor” and are therefore shorter
than the arc on the workpiece surface.
