Mechanical design of an indexed metrology platform for verification of portable coordinate measuring machines

摘要

The demand of faster and reliable measuring tasks for the control and quality assurance of modern production systems creates new challenges for the field of coordinate metrology. Thus, search for new solutions in coordinate metrology systems and development of existing ones that respond to industry's demands still persists. An example of such coordinate metrology systems are the portable coordinate measuring machines (PCMMs), which use in industry has considerably increased during the last years, mostly due to their flexibility for accomplishing in-line measuring tasks as well as their reduced costs and operational advantage as compared to traditional coordinate measuring machines (CMMs). In this work, the mechanical design of an indexed metrology platform (IMP) is presented. The aim of the IMP is to increase the final accuracy and radical simplification of the calibration, identification and verification of geometrical parameters procedures of PCMMs.
