Creating Virtual Machine Models with Quest
Adding Kinematics to the Model
Two axes will now be listed in the lower-right “Axes” window. Move the X-axis and C-axis
sliders to see the effect on the C-axis coordinate frame. The model navigator should appear as
shown above.
If non-zero values are used for the axes positions, objects attached to them will be in relation to
the offset position. The choice to use zero values (as done here) or to define axes at some position
(e.g., at the table face) depends on how the physical components of the model will be
defined (discussed in the next section).
Step 3: Associate axes with GENER
Creating the X-axis and C-axis defines them in the model, but if you ran a post processor or
control emulator with this model, neither of these axes would move. You must manually define
the association between model axes and the list of possible axes that CERUN and GENER can
control. You do this by selecting the Properties dialog of the top-level machine object (typically
“Machine01” unless renamed).
� Right-mouse on the “Machine01”
entry and select Property.
� Select the Axis Mapping tab.
� Double-click in the Model Axis
column in the X Axis row and
then choose “X Axis” (the
model axis name).
� Do the same for the C Table
axis, choosing “C Table Axis”
in the Model Axis drop-down.
� Select OK.
Manually associating model axes to
their CERUN and GENER counterparts
provides flexibility both in axis naming and in the orientation of standard axes. For example, a
horizontal machine model might use an X-axis to control the Z-axis column; in which case the Zaxis
control axis would map to the X-axis model axis.
On machines with multiple controller channels, there can be multiple axes of the same type. For
example, on a 4-axis merging lathe there will be two X axes and two Z axes. In this case, you
must create a second channel and assign the model‟s secondary turret X and Z axes to the
channel 2 X and Z controllable axes.
Lastly, if there are multiple spindles defined in the model, then they must be assigned as milling
or turning spindles for the appropriate channel. A milling spindle must also be assigned for VM
to correctly simulate boring bars and other 3D tool shapes.
