In order to improve accuracy, speed and traceability of co-ordinate measuring and to create a tool for research on new measuring strategies and for industrial application the IPA has developed a measuring system for sculptured surfaces which is integrated within a CIM system. This system connects model making, metrology, CAD/CAM and NC technology by standardized software interfaces. The measuring software package can be an enhancement to any CAD system open for user applications. By this means measuring and construction sessions take place within a common software environment and all of the CAD system's capabilities of visualisation and shape reconstruction can be used. The software has been adapted to two different CAD systems and is able to interact both with tactile CMMs and optical sensor systems.
