5.1 Simulation Mode of Operation
5.1.1 Graphic Elements, Displays
Graphic elements:
■ Coordinate systems
The zero point of the coordinate system
corresponds to the workpiece zero point. The
arrows of the X and Z axes point in the positive
direction. If the NC program is machining more than
one workpieces, the coordinate systems of all
required slides are displayed.
■ Displayed blank form
■ Programmed: Programmed blank form
■ Not programmed: ”standard blank form” (control
parameter 23)
■ Display of finished part (and help contours)
■ Programmed: Programmed finished part
■ Not programmed: No display
■ Display of tool
■ Programmed in the NC program: The tool
programmed in the REVOLVER (TURRET) section is
used
■ Not programmed in the NC program: The entry in
the tool list is used (see ” 3.3 Tool List, Tool Life
Data”)
The CNC PILOT generates the displayed tool from
the parameters of the tool database. Whether the
complete tool or only the ”cutting area” is shown is
specified in ”Picture number” (picture no.=–1 in the
tool editor: No tool displayed).
■ Chucking equipment display
The simulation graphics displays the chucking
equipment provided that it has been programmed
with G65.
The CNC PILOT uses the parameters of the
chucking equipment database to display a chuck.
■ White dot
The point of light (small white rectangle) represents
the theoretical tool tip.
■ Rapid traverse paths
Are shown as a broken white line.
■ Workpiece line display and tool path display
Tool paths are shown as a continuous line. They
describe the path of the theoretical tool tip. The
wire frame graphics is particularly convenient if
you only need a quick overview of the proportioning
of cuts. The path of the theoretical tool tip, however,
is not identical with the contour of the workpiece.
This graphic is therefore not as suitable if you wish
to run a thorough check on the machined contour. In
the CNC, this ”falsification” is compensated by the
cutting radius compensation.
