Extending the Octree Model to Include Knowledge for Manufacturing
Knowledge-based expert systems are emerging as an important tool in engineering development. These expert systems promise to shorten design cycles, facilitate design for manufacturaility, and provide cost savings. Current CAD systems lack rule based inferencing that uses geometric features. These systems, both 2-D and 3-D, lack the data structures which are amenable knowledge representation. We present a data structure, based on Octree representation and demonstrate its facility to compute, store, access, and manipulate 3-D manufacturing data in the form of features of the geometry and mass properties. We indicate how the knowledge can be used ins manufacturing methodologies such as process placing, design for assembly, etc.
