Application of the Next GPS Operation Technology in Flatness Error Evaluation

Operation and operator technologies introduced by Geometrical Product Specification and Verification(GPS) provide the necessary knowledge grounds for digitization and standardization of verification process of geometrical products . By explaining the basic ideas of GPS operation and operator technologies and also by taking the flatness error evaluation as an example, this paper illuminates the deficiency of the traditional flatness error evaluation method. Furthermore, the method and the key technique of digitized flatness error evaluation based on GPS are put forward.
