| Abstract: | Black box model for uncertainty estimation introduced by Geometrical Product Specification and Verification (GPS) provide the necessary knowledge grounds for specific and quick estimation of uncertainty in geometrical measurement. This paper explaining the concept of GPS black box model by contrast with the black box model in autocontrol field,systematically analyses the key technical problems for its application and finally illuminates its working mechanism with an example of CMM in uncertainty estimation. |
