5.2. Generation of core/cavity bloc

5.2. Generation of core/cavity blocksCore and cavity blocks can be generated based on the following steps.Step 1. Identify all the through-hole undercut features and patch’ up all these features.Step 2. Generation of a bounding box. The bounding box is defined as the material stock that fully contains the moulding with enough space for assembly of other components. Figure 10 shows the bounding box of a moulding.Step 3. Generation of parting surfaces and sewing’ all the parting surfaces together.Step 4. Subtracting the bounding box with the patched part solid by the BRDO and splitting the bounding box using the generated parting surfaces.
