Developing An Integrated System for CAD and Inspection Planning

Inspecting work-pieces dimensionally to ensure conformity to design criteria is an integral part of manufacturing. An inspection plan defines measurement and inspection requirements. Problems can arise, however, when the design intent is translated into a set of inspection instructions. Computer Aided Inspection Planning (CAIP) has been the research topic for the last many years. The integration between CAD and CAIP assist in inspection planning task to direct the operation of the inspection system using Coordinate Measuring Machines (CMM) for dimensional verification of the prismatic parts. The objective of the paper is (1) To address the issue of integration of CAD and inspection planning in which the prismatic features of design with inspection are linked efficiently (2) The generation and execution of inspection plans are through the incorporation of CAIP with CMM using DMIS code programming. DMIS is essentially a standard for the two-way communication of inspection data between computer systems and inspection equipment. Finally, a case study is presented to demonstrate and validate the integrated system.
