| Abstract: | Operation and operator technologies introduced by Geometrical Product Specification and Verification (GPS) provides the necessary knowledge foundation for digitizing measurement of product's geometrical error. This paper analyzes the operator formation for coaxiality error evaluation and provides the selective principle and present mathematical model of its least square evaluation. The paper realizes the digitizing measurement process of the coaxiality error of the multidiameter through an example. |
