Abstract :
This paper presents the mathematical definition of cylindricity tolerance and mathematical model for cylindricity error evaluation firstly, and then the mathematical models and efficient methodology are proposed for the evaluation of cylindricity error based on projection theory and geometrical approximation theory for geometrical error evaluation. The search technique is efficient and easy to code, and the simulation calculation results indicate that it can provide accurate results quickly.
