Abstract

New Geometrical Product Specification (GPS) developed by the ISO/TC213 is a series of macro and micro geometrical specification for the design and manufacture of products. According to the digitized theoretical foundation of new GPS, the important essential relationship between operations and cylindricity error is given. On the base of new GPS, verification operators to certain the benchmark for cylindricity error evaluation are constructed. In term of the minimum condition principle, the mathematical model of the cylindricity error and the optimal objective function are given, and then the modified simplex algorithm is used to search for the optimal solution of cylindricity error. In this paper an experimental example is presented, and the evaluation results verify the feasibility of proposed method. Furthermore, it is shown that the digital metrology method based on GPS is critical in realizing the digitalization, standardization and high efficiency of geometrical error evaluation.
