Research in progress on data base requirements is described for second-generation, integrated CAD/CAM systems. Syntactic pattern recognition is applied to the classification of holes from 2-D cross-sectional descriptions extracted from a 3-D solid geometric data base. The experimental system includes a program to extract an edge list of a hole from a solid data base and to code the cross section into a string representation. An Earley syntax analyzer/feature recognizer then classifies the string according to user-defined generic hole families.
