3.4.6. 3D-CAD Extension - Holder
To be able to use a 3D-CAD extension or a holder you must prepare a CAD file with practically
the same characteristics as for a 2D-CAD extension or holder:
The model can only contain a 3D model of the extension or holder.
The model??s CAD origin must be located:
At the machine??s spindle nose for a holder.
At the fastening point between the holder and the extension for an extension.
At the default origin in the CAD software.
The orientation of the CAD origin can be configured in NCSIMUL. The CAD model
will use the machine spindle as the orientation reference. For most milling centres the
Z axis corresponds to the spindle axis.
NCSIMUL calculates the height of the elements automatically.
For an extension the calculated height corresponds to the distance between the CAD reference and the lowest CAD element of the model, measured along the
revolution axis. This distance define the fastening point for next element (tool).
The calculated height of a holder corresponds to the distance between the CAD
origin and the lowest point in the CAD model measured along the revolution
axis. This distance define the fastening point for next element (tool or extension).
The elements are stacked automatically by NCSIMUL, end to end (CAD origin and fastening
point of next element). However the total value of the stack can be modified in the Parameters tab.
The source CAD file, the layers used to model the 3D-CAD extension or holder and the elemnt
orientation must be specified in the tool library.
