Abstract—A hole recognition algorithm for all hole types in a mold set is proposed. The algorithm can recognize holes of both circular and non-circular types, and blind and through types. It can also detect ladder holes, each of which is composed of a series of holes connected in sequence, and related holes that pass across different CAD models. The proposed hole recognition algorithm is divided into five steps: (1) facial composition is searched for each hole, (2) the holes are evaluated as either through or blind, (3) related holes are detected on each CAD model, (4) related holes passing across different CAD models are detected, and (5) data is output. Three mold sets were used to demonstrate the feasibility of the proposed method, and the results were compared with those from commercial software.
