Information Technology Reference
The user consults with the KBES for determination of appropriate machining units and then
s/he uses the CAD system for designing the required SPM. The CAD system used in this
work is SolidWorks which provides user with a 3D modelling environment. It is customized
for SPM design by developing a feature library containing 3D models of standardized SPM
components. As shown in Figure 12 the feature library contains a number of folders, each
containing a group of SPM components. When the user wishes to insert a component, s/he
simply opens the corresponding folder and double clicks on the desired component.
Component's model is extracted from the library and can be easily placed in the desired
position and orientation within modelling environment. Figure 13 shows different 3D solid
models of quill units (MONOmasters) restored in the feature library, and Figure 14
represents the major steps of processing a typical drilling operation and the way that
various components of the system are used in different activities.
