Abstract: | Coordinate measuring machines (CMMs) have been widely accepted and are increasingly used for carrying out inspections. With
the increase in complex designs and tighter tolerances, the inspection process involving a CMM has become critical and there
is a need to plan it effectively. In the present work, an object oriented planner for the inspection of prismatic parts (OOPIPP)
has been developed. It incorporates interactive feature recognition and carries out all the essential steps of inspection
planning, that is, selection of the most stable part orientation, arriving at number and distribution of inspection points,
feature accessibility analysis, sequencing of probe orientations, removal of duplicate faces, and, finally, sequencing of
faces. Various relationships between different entities of the system and distinct features of OOM have been used to develop
the algorithms of different modules. Fuzzy logic for decision making has also been applied and a suitable method of combining
fuzzy sets has been used for the selection of part orientation and for sequencing probe orientations. |
